Troubleshooting

I can't receive and send emails from the mailbox hosted on my domain

Most Yandex Mail issues have to do with incorrect mail domain settings. Make sure that the domain is set up correctly:

Step 1. Check the domain expiration date

You can do this by using any WHOIS service, such as https://www.whois.com:

1. Go to the WHOIS service page.

2. Enter your domain name in the search box, like example.org.

3. Make sure the date specified in the Expires On: line hasn't been reached yet.

If the domain expired, contact your registrar to renew it.

Step 2. Check the DNS records of the domain

Make sure that your DNS records are configured correctly. You can do this at https://www.digwebinterface.com or by using any other dig utility.

MX

SPF

DKIM

1. Go to https://www.digwebinterface.com.

2. Specify your domain name (such as example.org) in the Hostnames or IP addresses field.

3. In the Type field, select MX and click Dig.

The response should look like this:

example.org.  20755 IN MX 10 mx.yandex.net.

If the server doesn't respond, the response doesn't match the request, or it contains too many records, the MX record wasn't properly configured. Follow the instructions to set it up.

Examples of incorrect responses and how to correct them

Response	How to fix it
example.org. 20755 IN MX 10 mx.yandex.net. example.org. 12345 IN MX 12 somevalue.somedomain.tld	Delete extra records, leaving only one with priority 10 and value mx.yandex.net.
example.org. 12345 IN MX 12 somevalue.somedomain.tld	Delete this record and set up a new one following the instructions.
The response is empty.	Most likely, the record was not configured for your domain. Follow the instructions to set it up. If the record is configured but doesn't appear in the response, contact your hosting support.

Alert

Wait 72 hours before checking the DNS records again. DNS servers need this time to update their record data.

1. Go to https://www.digwebinterface.com.

2. Specify your domain name (such as example.org) in the Hostnames or IP addresses field.

3. In the Type field, select TXT and click Dig.

The response should look like this:

example.org. 21600 IN TXT "v=spf1 redirect=_spf.yandex.net"

or

example.org. 21600 IN TXT "v=spf1 ip4:IP-1 ip4:IP-2 ip4:IP-3 include:_spf.yandex.net ~all"

If the server doesn't respond, the response doesn't match the request, or it contains too many records, the SPF record wasn't properly configured. Follow the instructions to set it up.

Alert

Wait 72 hours before checking the DNS records again. DNS servers need this time to update their record data.

1. Go to https://www.digwebinterface.com.

2. In the Hostnames or IP addresses field, enter the mail._domainkey subdomain name for your domain, for example mail._domainkey.example.org.

3. In the Type field, select TXT and click Dig.

The response should look like this:

mail._domainkey.example.org. 21599 IN TXT "v=DKIM1\; k=rsa\; t=s\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDlk+IUXTHUIumVpG1S0vwFuwO9AC2aRrJj21MLj7xvO0Brys/fDxOTaFsoVsA2/t9mcxf1kqx/bCsEvJiiOUUw5eihQefcY7xJoeruJK/o+IKU2dTO9OOPfSyqGLuQ+v/DMJRjhz73XOpkPOpPwLhQKhvBLNM2TCxPqCL0E42/7wIDAQAB"

If the server doesn't respond, the response doesn't match the request, or it contains too many records, the DKIM signature wasn't properly configured. Follow the instructions to set it up.

Alert

Wait 72 hours before checking the DNS records again. DNS servers need this time to update their record data.

If your domain registration hasn't expired and all the settings are correct, look for the issue in Yandex Mail Help under Issues sending and receiving email.

My emails don't reach the recipient or end up in the spam folder

If you send too many emails from your mailbox, the Yandex Mail security system may mistake your emails for spam and stop you from sending them. To learn more about outgoing email limits and requirements for mailing lists, go to Sending a large number of messages in Yandex Mail Help.

If you didn't send any mass email messages, try to identify the problem using the step-by-step guide in Yandex Mail Help under I can't send email.

I've set up message filters for mailing lists, but the emails don't reach the recipients

For example, you've set a message filter according to which an email sent to a specific mailing list should be deleted from the recipient's mailbox:

If the filter worked, but the email was also supposed to reach other mailing lists (or no message filters were set up for them), then the email won't reach the recipients of any of the mailing lists. For the emails to be delivered, edit the filter conditions.
