ATMC's Email ServicesListed below are services to enhance your online experience. These services apply to both dial-up and broadband Internet accounts .
ATMC offers a robust service available with our new advanced webmail application. Supported protocols include: webmail, POP and virtual email and more. Email Forwarding: This will allow you to have email forwarded from accounts within ATMC's Internet service to other accounts which could include: email within a different domain, a different account within your domain or another email service entirely. Virtual Email Accounts: Some users may have specific requirements for multiple email addresses. Virtual email accounts accomplish this need. ATMC provides you the ability to alias general accounts such as email@example.com or firstname.lastname@example.org to a real person such as email@example.com. These may be set up under Preferences > Settings> Identities in ATMC Webmail. Virus Protection
The amount of damage viruses can do to your computer or network range from annoying to catastrophic. Viruses have gone from being an annoyance to being highly sophisticated, dangerous, and malicious. Therefore, they must be dealt with seriously, constantly and vigilantly.
Why was my message blocked as spam?Our spam filters use a variety of criteria to determine if a message is spam. If a legitimate non-spam message you have attempted to send or receive was misclassified as spam, you may submit the message to our support team, and in most cases we should be able to correct the scoring, with a small number of exceptions. The following are typical reasons why a message might be blocked as spam:
- The message is forwarded spam message or contains excerpts of spam, or quotes other spam features. This is usually the only case that is not easily corrected. You should expect that forwarded spam will score high. Messages that mention specific spam features -- such as a message warning about email scams and mentioning specific characteristics of that message -- will often be blocked because those specific characteristics may be something the spam filter is looking for. Note that certain types of emails like 3rd party spam quarantine digest summaries (which mention spam subjects), or mail & web server log summaries (which may mention spam domains or email addresses) may be blocked due to mentioning those known spam features.
- The message mentions a legitimate domain that was blocked due to associated spam activity. For example, certain web sites may be hacked by a spammer, and used to store spammy web content that is referenced later in spam messages. These domains may be included in the spam filter when they appear in spam. If we determine that a domain flagged as spammy for this reason is really legitimate, we can remove it from our spam definitions. Other identifiers (e.g. a phone number or street address) associated with spam emails may be similarly flagged. If determined to be legitimate, these will be removed from our spam filters.
- The message contains legitimate content that is superficially similar to spam content may be mistaken for spam. For example, a legitimate email concerning a financial transaction might be similar enough to a money transfer scam to have a high score. Usually the spam classifier can be adjusted to correct the scoring.
- The message does not have any obviously spammy content, but nonetheless was classified as spam. This can happen in some circumstances because the spam classifier makes a probabilistic calculation based on how frequent certain features (e.g. words) appear in spam messages versus legitimate messages. While this classification mode is very accurate, it is possible for statistical outliers to occur that are classified as spam without any obviously spammy text. The situation is analogous to what happens when you flip a fair coin 20 times, record the number of heads and tails, and then repeat the 20-flip experiment many times. On most attempts you expect to get approximately half heads, half tails. But if you try enough times, you will on rare occasions get sets with almost all tails. When this occurs it is not an indication the coin is "broken", it is just a statistically improbable event that has been observed. Similarly, legitimate messages may be scored as spam due to a skewed feature probability distribution. As in the previous case, this type of scoring problem may be corrected by adjustments to the spam classifier.
How do I check my email from another computerYou can check your email using our Web based email at ATMC Webmail http://webmail.atmc.net with your browser. Just type your username and password and click log in.
If you are unable to check your email , check your username and password. Make sure that you have the correct username and password set. The username or account name is your unique username you chose. Your username is your email address (firstname.lastname@example.org). The password is the same password that you use when connecting to the Internet. Username and password should be typed in correctly. If you are unsure of your password, you may contact a Customer Service Representative at 754-4311 (verification is required before passwords will be released). If your username and password are correct, and you still cannot access your email, contact our repair department at 754-4317 to open up a trouble ticket.
If you can access, send and receive email. The problem is with your email software or a particular message. Make sure that your email software is set up correctly. Outgoing mail server should be set to: smtpauth.atmc.net. Incoming mail server should be set to: mail.atmc.net.
Create a Strong PasswordCreating a strong password helps protect your email account. Strong passwords should be 8 characters long and include at least one:
- uppercase letter A-Z
- lowercase letter a-z
- number 0-9
- symbol !@#$^*,.>_<
Unable to Receive EmailsLarge or corrupt email on the server:
Most likely there is an email that is too large or corrupt on the server. Usually when this happens you will see the email program connect to the server and start downloading files but will stop or lock up before all of the emails are downloaded. To fix this problem, log on to http://webmail.atmc.net/ and delete the oldest email sitting in you mailbox, log out and then try to access your email through your email software package again.
Your computer disconnects you from the Internet while trying to receive emails:
This usually occurs as a result of your Internet settings. Disconnect settings in Internet Explorer can cause your computer to experience frequent disconnects when downloading large files or downloading email.
Unable to Send EmailsIs the Email Address correct?
If your email settings are correct and you were able to send/receive email before, verify the email address of the person you are trying to email. You may want to have them send you an email and then reply to their email. If you are able to reply to that person's email, but unable to send them a new email, then the email address is enter wrong..
Is there an email sitting in your Outbox? The most common problem experienced by users is an incorrectly addressed email message sitting in your Outbox. Most email programs will hold email messages before sending them. If one message is incorrectly addressed, the mail server will refuse to send it and all subsequent email messages will not be sent. This problem is common in Outlook software as well as some Netscape email, Internet Mail, etc. To fix this problem you will need to launch your email software and go to the Outbox folder. See the list of all email waiting to be sent. Double click on the first email message to open it. Check that the email address is correct. The email should consist of a valid username at a valid domain name. There cannot be any spaces between the characters. If this does not work or you are unsure of the email address, then delete the first email in your Outbox and try sending the remaining emails. If you are still unable to send emails, delete all emails in your Outbox and reply to an email you have been sent. If you are able to reply to that email, then the email address entered in one of the messages that were in your Outbox was wrong.
Large E- mail Attachment: If your settings are fine and email addressed correctly, then make sure that the email you are sending is not larger than 30MB. ATMC limits the size of email attachments that can be sent or received to 30 MB. If the file that you are sending is too big, try compressing it. Good software to compress files is WinZip. The receiver should have the same software to be able to decipher the message.
No Relay Error: If you are connected to another provider and trying to send email through mail.atmc.net you will not be allowed to. Most ISPs do not allow relaying through the mail server. Incoming mail server recognizes you by your username and password, so you can check your email no matter what provider you are connected through. Outgoing mails server, the server that handles sending of your email, recognizes you by the IP address, the unique IP address that you are assigned when you connect to ATMC. When you connect to another provider our SMTP server will not recognize you as an ATMC user. You will need to use the SMTP Outgoing Mail server of the provider you are dialed into.
People say I am sending them a virus, but I have not sent them an email
A worm virus can send infected emails without your knowledge. You do not have to create and send, or even forward, an email with a virus attached for other people to receive the virus from you. Certain viruses called worms, when executed automatically sends email with the virus attached to all addresses listed in the infected user's address book.
ATMC cannot guarantee, nor take the responsibility for, virus protection on your system, therefore sole responsibility for virus protection lies with the end user. For information on how to clean the virus and prevent future infection, see Virus information. If you need additional assistance, please contact your computer manufacturer or a computer repair shop for professional help with viruses.
Important Email Security Tips:
- Never respond to an email asking for personal or financial information such as your email address, password, Social Security Number, etc. (ATMC, PayPal, and your bank are examples of companies that would never ask for personal information in an email.)
- Don't open an email or attachment from someone you do not know or trust.
- Never click on a link or executable file within an email from a company or organization that you do not trust.
- Do report 'suspicious' email by forwarding it to email@example.com
- Do keep security software and operating systems currently updated.
Email SecurityEmail has become an integral part of most of our lives. For many of us, it may be the most common way we communicate with others. Long gone are the days when email was simple text transactions between two users looking at black and white terminals. Today's users expect crisp fonts, colors, inline images, background patterns, HTML and other browser specific formatting as well as the ability to attach moderately sized files to their messages. The evolution of email technology that allows all of these new features has greatly enhanced the experience of email users, but has brought along with it some very common and serious security concerns. Email has historically been the most common method for attackers to get malicious code to unsuspecting users, and while many new and creative tactics are being employed, this method is still frequently use to propagate malicious code.
Email AttachmentsThroughout the evolution of email and all the resulting additional features, it is likely that the most prominent would be the ability to "attach" files to email messages. While these changes certainly make the transport of such files simpler and email more useful, they also introduce some technical and security concerns. Email was not designed with these large attachments in mind and actually handles them quite inefficiently. In addition to the inefficiencies of transmitting files this way, it is a huge security risk for users to allow files of unknown origins onto their PC. As many email applications continue to allow more and more "web functionality" directly within the email program, more options are available to attackers. Users should be very cautious when opening email attachments, even from trusted sources. In best practice, email users should only download or open attachments from a recipient that they know and trust, as well as confirming they know what the attachment is before opening it. Opening any unknown email attachment (even from a trusted sender) can immediately infect your PC with malicious code. Some infected machines will further utilize their host's mail application to spread the infection by emailing individuals in that machines address book.
ATMC's feature-rich webmail provides its users additional security from storing possibly infectious code on their PCs. Our email network spam filtration will keep the majority of spam and malicious emails from ever reaching the inbox. Any suspicious email that may reach the mailbox can be deleted on our servers before it ever reaches your PC's hard drive.
Loading Web-Content Inside of Email MessagesSome email messages contain images and web content directly in the body of the email. By default, ATMC Webmail will not load these external pages.
This content, if loaded, can validate the existence of an email address to an attacker. A common technique used by spammers is to send out messages blindly to "guessed" email addresses (which are generated from "dictionary" lists or purchased from old spam lists). Once a spammer confirms that an address is valid, it gets moved to an even higher value list in the spam community and will be targeted for even more spam.
Many recent internet attacks have been based on browser or web code exploits. Once attackers find these exploits, they can quickly spread across the internet and will often take users completely by surprise by loading pages inside innocent looking emails. Disallowing the auto loading of external content within email messages provides an additional layer of protection to users.
Clicking on Links or Executable Files Within EmailsMany spam or other malicious messages contain links to websites or even executable files. If you get an email from someone you don't know or a company or organization that you did not subscribe to content from, do not click on links within the body of the message. In the best case scenario, these links may lead to a site and drive up advertising revenue for a site that could use this income to propagate even more malicious behavior. In an even worse scenario the site this link leads you to may contain code that can compromise your PC.
It is never a good idea to run an executable file sent via email. Most respectable vendors will send software with a proper installer for your operating system that is digitally signed for that company. Any time a user elects to run an executable file, that application has access to the PC and could be executing malicious code or installing other code that may run silently in the background.
Mailing Lists and Electronic AdvertisementsATMC strongly enforces responsible business and personal email practices requiring that all electronic mailings be CAN SPAM compliant. The guidelines described in this law are minimum guidelines for individuals who wish to send advertisements or any other customer communications. Businesses or civic organizations wishing to conduct business via email are strongly encouraged to maintain their businesses online reputation by adhering to even higher standards by utilizing effective software that requires their recipients to "double opt-in" to their email lists and providing timely responses to unsubscribe requests. There are many companies that provide these types of services to businesses and organizations at low cost, as well as providing access to software or online tools to manage these activities. Any users found to be in violation of these practices can have their email services and/or broadband service suspended immediately. To protect email service for all of its users and to maintain a reputation as a responsible ISP within the internet community, ATMC will enforce all aspects of its Acceptable Use Policy.
Note: Do not attempt to unsubscribe from email communications that you did not sign up for. This can validate that your address is valid and cause you to be targeted for more spam.
Response to Spam or Phishing EmailsDespite the exhaustive efforts that ATMC employs to limit spam, there will likely be occasions where every user will receive some sort of Spam message or Phishing email (a fraudulent attempt to elicit personal information by misrepresenting a reputable agency). Often users unfamiliar with these threats are not sure how to handle these communications. Please reference the list at the bottom of this document for valid addresses to report such emails. Most importantly, never respond to such an email. No good will ever come of validating your existence or a successful delivery of unsolicited emails.
ATMC Webmail users can simply select the message and click on the SPAM button on the webmail toolbar to report a message as spam.
Reporting Suspicious Email CommunicationsIf you receive a phishing email which is asking for your personal information such as any account information or passwords DO NOT RESPOND TO IT. Please forward it to firstname.lastname@example.org. ATMC will never ask for personal information via email and strongly recommends that our users do not relay such information to any company via any insecure methods.
For webmail users receiving a spam email in your inbox please click the "SPAM" button to report it as spam. If you receive an email in your SPAM folder that is not spam or junk click the "Not SPAM" button.
If you are using a third party email client such as Microsoft Outlook or Outlook Express and you receive an email that is spam please forward that particular email to email@example.com.
