Spam means unsolicited mail that may come to your email address. It may contain advertising, “chain letters”, computer viruses, or even be a phishing attempt. To create a base of addresses, spammers use software which matches email addresses with the help of a special dictionary or gathers addresses published by users on publicly open websites.
Unsolicited mail should be differentiated from honest mail. The features of the fair mailing lists are provided in the document Requirements of Yandex to fair mailing lists.
Yandex.Mail filters not only incoming but also outgoing mail. Every message is checked by Dr.Web antivirus. Messages in which a virus is detected will be rejected by the mail server and the sender will receive a report.
If you think you have received a spam message in your Inbox, select the message and click It's spam! and it will be moved to Spam and the required information will be sent to Anti-Spam. Studying unsolicited mail helps improve filtering algorithms for new types of spam.
If a message gets into Spam by mistake, click Not spam! and new messages from the mailing list will go to the Inbox.
Anti-Spam takes into account both general and “personal” filtration rules which apply to specific mailboxes. Any messages that you believe to be unsolicited but another mailbox user finds useful will be filtered into Spam in your mailbox and into the Inbox of the other user's mailbox.
You may receive suspicious messages which usually are not spam. For example, you will not see your address in the To or Cc of the message header if the sender has added your address to a Bcc copy. In some cases, this may happen if another mailbox is configured to forward messages to your address. If forwarding is set up by someone other than by you, contact the administration of the server which hosts the mailbox forwarding the message and attach a copy of the message with all mail headers.
If duringregistration you get the address email@example.com, but in the email that was sent to you, in the field To the address is firstname.lastname@example.org, email@example.com, firstname.lastname@example.org or similar, it means that the email was sent to one of your mail aliases.
If you have received a message intended for someone other than you, the sender may have confused the address when sending it or during registration at the website. Contact the sender or the website administration to report a mistake.
If you are notified that a spam message has been received from you, check your computer for viruses with free antivirus programs such as CureIt! from Dr.Web and Virus Removal Tool from “Kaspersky Laboratory”. Then change your password.
You might also receive a spam message with your own address as the sender's address or a report that the delivery of a message failed, even though you had sent nothing to the given address. This happens because spammers enter forged addresses into From and Reply-To. Your address may end up in a database of fake addresses without spammers having access to your account. The base is created by trial and error with the help of a special dictionary or populated by searching addresses that users publish on publicly open websites.
Users may be confronted with this situation regardless of which mail service they use, because some mail servers do not follow sender identification requirements. If you receive such a message, select it and click Its spam!to include it in the spam filter.
Check your Session history to make sure that nobody has sent messages from your mailbox other than you.
