    In version 76, when the license is deactivate, all mail services stop, sometimes we renew the license a few days later and we will not receive any mail for a few days.

    This is an unacceptable limitation.

    Hello @vacancy,

    It's important to note that any feature or service associated with the cPanel & WHM installation is not guaranteed to work if the license is not valid. If you find that your license is expiring unexpectedly, the better approach is to troubleshoot and determine why that is happening.

    As far as the email issue itself, can you provide some more details about the specific behavior you encounter upon the license expiry? Do you notice any output to /var/log/maillog or /var/log/exim_mainlog when attempting to send or receive an email?

    Thank you.

    When we send mail to an address on the server, the following error is returned.

    After the license is expired, imap and dovecot services are failed notification e-mails.

    Code:
    2018-11-20 22:14:54 1gPBU4-0005P6-O5 == info@mailuser123.com R=virtual_user T=dovecot_virtual_delivery defer (-44): LMTP error after RCPT TO:<info@mailuser123.com>: 451 4.3.0 <info@mailuser123.com> Internal error occurred. Refer to server log for more information.

    Hello @vacancy,

    Internal case CPANEL-24022 is open to determine if this behavior is by-design as of cPanel & WHM version 76, or if it's unintended. I'll update this thread with more information on the status of this case as it becomes available.

    Thank you.

    Hello @vacancy,

    To update, the case was accepted and a fix to ensure email delivery works when the cPanel license is invalid is tentatively planned for a future cPanel & WHM version 76 build. I'll continue monitoring the case and update this thread with more information as it becomes available.

    Thank you.
