imap and exim constantly fails on the latest release 11.25

I tried to add port 26 to SMTP_PORTS in CSF and dovecot/imap restarted successfully

How come that dovecot listens to por 26? Arent SMTP should always listen to port 25?

I dont encounter this issue in 11.24. Did cPanel change the port for dovecot to 26 in 11.25?

If you would like we can take a look at the issue for you if you submit a support request with the specific details involved (copies of the e-mail headers will also help); when available, please PM me referencing this thread and your new ticket ID number so I may follow-up internally.

For reference, by stock-default the Dovecot configuration is not configured to listen on port 26. Dovecot in a cPanel/WHM system is used for providing IMAP and POP access, not SMTP.

Port 26, like port 587, is a commonly-used alternative to SMTP port 25; it is not uncommon for a server administrator to configure Exim, the SMTP mail server/MTA, to listen on an extra port (e.g., 25 and 26, or 25 and 587, etc.).

The extra port for Exim may be configured using the following menu path in WHM:
WHM: Main >> Service Configuration >> Service Manager >> exim on another port
Documentation: Service Manager

I see. I don't check the exim on another port as enabled in service manager although port 26 is there. But i have another server using dovecot but its not listening to prot 26 as I didnt add 26 in SMTP_PORTS in CSF.

Is there any other configuration file that could possibly configured exim to listen to port 26?

The following commands should help to locate potential locations for Exim port customizations:

# grep -Hin "daemon_smtp_ports\|tls_on_connect_ports" /etc/exim.conf /etc/exim.conf.local
# grep -HinR "exim" /etc/chkserv.d

What is the output of the following command?

# lsof +c0 -anPi4:25-26,465,587,110,143,993,995

Here is an alternate command that filters output by the process command name instead of port number; this could be used to compare output without needing to know the port numbers:

# lsof +c0 -anPi4 -c/courier\|dovecot\|exim\|imap\|pop/ix
