The full message headers contain detailed information about the email message:

• Exact time the message was sent and delivered
• Encoding
• Type of message
• Message path from the sender's server to the recipient
• Protocol through which the message is received

Information from the message headers can help fight spam or resolve a technical issue with your mailbox.

For Yandex Mail to work correctly, enable JavaScript support in your browser.

If Yandex Mail is undergoing maintenance, you will see the message Our servers are currently undergoing scheduled maintenance. Therefore, you can currently only use your mailbox to read and send messages at the top of the page (in the two-panel interface) or in the bottom left corner of the page (in the three-panel interface).

During maintenance, your mailbox is only available for sending messages or viewing those you have already received. You can't make any changes, for example, move messages to other folders or change mailbox settings.

The “read-only” mode may display an outdated status of your mailbox. If you have received or sent messages, they won't appear in the list of messages until maintenance has been completed.

On completion of maintenance, mailbox details will be updated and all messages received and sent during maintenance will be visible.

To hide sender profile pictures from each line of the message list, open the menu Settings  → Other, turn off show contact profile pictures, and save changes.

Captcha numbers appear when logging into your mailbox if:

1. A wrong username or password has been entered several times in a row. Make sure the data you are entering is correct. If you are using a mail program or a built-in email client in Opera, make sure your details are entered correctly.
2. If your LAN settings allow several users to use one network address, Yandex identifies them as one visitor. In this event, captcha numbers may appear if other users' attempt to log in to Yandex in your network failed. Contact your network administrator to solve the problem.
3. Many similar letters were sent from your mailbox — our system considers your account suspicious. To learn more, see I got the message “This message cannot be sent because it looks like spam”.

You should also check your computer for viruses because some malware is used for automatic password matching.
