Fighting spam

Spam is unsolicited email that may be delivered your 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. To find out how honest mailings and spam are identified, see Yandex requirements for fair mailing lists.

Yandex.Mail uses the “Anti-Spam” service, which learns from user-submitted spam complaints, to recognize spam. It puts suspicious email with spam features in the Spam folder.

Note. All messages in the Spam folder will be automatically deleted in 10 days. Note that you will not be able to recover the deleted messages.

Yandex.Mail filters not only incoming but also outgoing mail. Every email is checked with ESET antivirus. Messages in which a virus is detected will be rejected by the mail server and the sender will receive a report.

Spam ends up in my “Inbox”

If you think you have received a spam message in your Inbox, select the message and click Spam! and it will be moved to Spam and the required information will be sent to Anti-Spam.

After submitting several complaints about the same kind of message, Anti-Spam starts putting all similar email into Spam. Mark all the email you think is spam by clicking It's spam! until all such messages are sent to the Spam folder instead of your Inbox.

Tip. Send unsolicited emails to Spam one by one. All email from one sender that gets moved to the Spam folder at one time is considered as one complaint.

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.

I receive a lot of spam in the Spam folder

If you receive a lot of spam in the Spam folder, it means that Anti-Spam works. If the email is really suspicious, leave it in this folder — it will automatically be deleted in 10 days. If the folder contains email you need, restore it.

Suspicious messages

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 was set up by someone other than you, contact the administrator of the server hosting the mailbox that forwards your emails and attach a copy of the email along with its properties.

Attention. Spammers often enter recipients' addresses in Bcc. Be careful when receiving such messages.

If you signed up for the address alice.the.girl@yandex.ru, but an email you sent has another address in the To field, such as alice-the-girl@yandex.ru, alice.the.girl@ya.ru, alice.the.girl@yandex.com or something similar, it means that th email was sent using one of your email 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.

I got a message saying that my email was not delivered (when I didn't send one)

You may get an email non-delivery report at an address that you didn't send anything from. This happens when spammers enter fake addresses in the From field and Reply-to hidden field. Your email address may have ended up in a database of fake addresses; spammers don't even need 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 of any mail service may come across dangerous situations since not all servers that handle mail delivery meet sender identification requirements. If you receive this type of email, select it and click Spam so that Yandex can improve its spam filtration.

Check your Session history to make sure that nobody has sent messages from your mailbox other than you.

Spam was received from my address

If you are informed that you have received spam or if you receive spam emails from your own email address, the reasons for may be:

Malware infection of your computer
If the computer was infected with a virus, your Yandex.Mail account might have been hacked. Check your computer for viruses using free antivirus programs, like CureIt! from Dr.Web and Virus Removal Tool from “Kaspersky Lab”. Then change your password.
Spoofing (forged mail headers)

Check if the email is located in the Sent folder. If the email is not there, it means that someone is sending spam with your email address specified as the reply address.

You might also get a message from the “Mailer-Daemon” service with an automatic email non-delivery report for an address that you didn't send anything to.

This usually happens because of spoofing. Spoofing is a type of internet scam, with the aim to distribute information in the form of unsolicited advertising (spam). Spammers enter fake addresses in the email properties (such as From or Reply to). They do not actually have access to your mailbox, but they use your address instead of the real address of the sender.

If you receive this type of email, select it and click Spam so that Yandex can improve its spam filtration.

Check your Session history to make sure that nobody has sent messages from your mailbox other than you.

The mailing list does not reach recipients on Yandex

If you send mailing lists to Yandex mailboxes and the emails were rejected by the Yandex mail server, you will receive an automatic report from “Mailer-Daemon” with the reasons for non-delivery and the name of the server which rejected passing the message to its destination.

Unsolicited mail should be differentiated from honest mail. To find out how honest mailings and spam are identified, see Yandex requirements for fair mailing lists. Yandex.Mail reserves the right to treat messages from mailing lists that do not comply with the mandatory requirements of this document as Spam or completely decline their delivery. Note also that meeting the optional requirements will significantly reduce the risk of your messages being marked as Spam.

I keep receiving the message “Message cannot be sent because it looks like spam”.

If you receive the error message "Message cannot be sent because it looks like spam" (“Spam limit exceeded” or “Message rejected under suspicion of SPAM”) or a prompt to enter a captcha code, this may be caused by the following:

Messages that are similar or use a template are sent out

Messages that are similar, use a template, or contain commercial or advertizing proposals are sent from your mailbox. Yandex.Mail doesn't allow you to send these types of email. Our service is intended for actual communication between people.

Tip. If you want to send out mass emails to your partners or clients, please use our special mailing services.
The daily limit on how many emails you can send was reached

Every day a huge number of emails can be sent from your mailbox, which can be regarded as spam. The emails can be sent both with your involvement and without your knowing about it.

In order to avoid this, Yandex has limits on emails sent per day.

Yandex.Mail limits

You can send up to 500 emails from one mailbox in a 24-hour period. If the email has several recipients, then each individual email sent counts separately towards your total.

Additional limitations are set on the number of recipients:

Number of recipients Restriction
Total for all email in a 24-hour period 500
In one email sent from the site 50
In one email sent from a mail client or over SMTP 35
Note. Limits can be lowered if Anti-Spam notices the mass emailing of similar messages, templates, spam, advertising, or commercial offers.
Restrictions on Yandex.Mail for domains

You can send 3000 * emails from one mailbox in a 24-hour period. If you entered several recipients, a separate email is sent to each of them.

Additional limitations are set on the number of recipients:

Number of recipients Restriction
Total emails in 24-hour period (from one mailbox) 3000 *
Total emails in 24-hour period (from all mailboxes of a single domain) 5000 *
In one email sent from the site 50
In one email sent from a mail client or over SMTP 35
* Only external recipients are considered. Owners of mailboxes in this domain are not considered.
Note. Limits can be lowered if Anti-Spam notices the mass emailing of similar messages, templates, spam, advertising, or commercial offers.
Your account was marked as suspicious

Our security system flagged your account as suspicious. Usually this happens if you didn't link a phone number to your mailbox or a fake name was entered in your Yandex.Passport.

Emails are sent to non-existent addresses.

A large number of emails were sent to nonexistent addresses from your mailbox. If email is sent to an address that doesn't exist, you receive an automatic non-delivery report .

We received a complaint about a mailing sent from your email address

We received several complaints from users about spam sent from your email address.

If this occurred, sending email from your mailbox will be blocked. Only sending emails is blocked. You will be able to log in to Mail and receive emails. If you don't try to send email during this time, the block is automatically lifted after 24 hours — otherwise the block is extended for another 24 hours.

While you are waiting for the block to be removed, follow the recommendations below to avoid similar issues in the future:

  1. Check your computer for viruses using free antivirus programs, such as CureIt! from Dr.Web and Virus Removal Tool from “Kaspersky Lab”. Then change your password.
  2. Enter your valid personal information on your Yandex.Passport page and link your phone number to your account on the Mobile numbers page.
    Note. If you use Yandex.Mail for a domain, enter the exact data for all the domain mailboxes.
  3. Make sure the your recipients addresses are entered correctly and remain active.
  4. Make sure that recipients of your emails have voluntarily agreed to receive them.

I get the error “Message rejected under suspicion of SPAM” in the mail client.

If you receive “Message rejected under suspicion of SPAM”, it means that Yandex.Mail determined that the contents of your email were spam. To resolve the problem, open the Yandex.Mail web interface and send a test email. This shows the system that messages are not being sent by a robot.

Also, check your computer for viruses using free antivirus programs, like CureIt! from Dr.Web and Virus Removal Tool from “Kaspersky Lab”.

For more information, see the I got a message "Email can't be sent" section.

Non-spam messages arrive in the “Spam folder”

If a non-spam message arrives in the Spam folder by mistake, select it and click Not spam!. This email is then moved to the Inbox folder. After a while, all emails from this address will start arriving in the Inbox folder again.

Make sure the mail filters don't move such messages to Spam. If any filter does this, disable it.

The Not spam! button doesn't work

Emails may end up in Spam if you use certain mail clients to manage your Yandex.Mail (such as Microsoft Outlook, The Bat!, or Thunderbird for desktop or Mail.Ru, Gmail, or Mailbox for smartphone or tablet). Some mail clients have built-in anti-spam filters that may send emails to the Spam folder.

If the Not spam! button does not work on the Yandex.Mail site, click it in your mail client or in the app (it may have a different name in different mail clients). Also disable the Spam check in the settings of your mail client so that emails aren't sent there automatically.

If the program has no spam filter, then change the password to your Yandex mailbox. Changing your password may help if you set up the program earlier and don't currently use it, but the program is still running and continues to send emails to Spam.

How can I unsubscribe from mailing lists?

If you have signed up for a newsletter from a site or service and no longer wish to receive email from them, you can unsubscribe right from your mailbox. To do this, open any email from the mailing list and click Unsubscribe:

After you click the button, the selected message will be moved to Trash. Messages from this mailing list will stop coming to your mailbox.

Attention. If the unsubscribe procedure was unsuccessful (for example, a wrong unsubscribe link was provided in the message or the request was processed incorrectly by the website or service), messages from the mailing list will continue arriving in your mailbox but the messages will be filtered as Spam.

If the email doesn't have a Unsubscribe button, add the sender's address to the blacklist or configure a mail filter that deletes email from this sender.
