Hi,
Suddenly stop sending emails and start having these errors in CPANEL: retry time not reached for any host for 'any_domain.com', someone could help me find the error, I have generated a ticket 93498586.

I have checked with my provider and no changes have been made.
I found this in the cpanel logs:

[2020-06-15 20:57:37 -0500] warn [whostmgrd] The subprocess (whostmgr (partial)) exited with an error: El subproceso informó el número de error 1 cuando finalizó. at /usr/local/cpanel/Cpanel/Server/Handlers/SubProcess.pm line 250, <GEN51> line 12.

I have cleaned the exim db, restarted the services and the problem persists.

Any idea?

Thanks.

Hello,

I took a look at the ticket you'd opened and it would appear that the issue was related to port 25 not being open. I wanted to also point out that you can have exim listen on 26 if your provider closes 25 - but it does appear that the end result of the ticket was that you would be contacting your provider for assistance.
