Posted January 4, 20241 yr rDNS/PTR = svr.miservidor.com Querido Sandep, ¿cómo estás? Tengo un problema y no entiendo la lógica. Antes mis clientes se conectaban a través de Thunderbird con la siguiente configuración Servidor entrante: mail.myclient.com Usuario: usuario1@myclient.com Puerto Imap: 993 Servidor saliente: mail.myclient.com Usuario: usuario1@myclient.com Puerto SMTP: 465 pero de un momento a otro dejo de funcionar mail.myclient.com (dejo de funcionar) ahora solo funciona con esta entrada y salida svr.myserver (ahora solo funciona este) Gracias Edited January 4, 20241 yr by jonathanm
January 4, 20241 yr if you check the ssl for the hostname, is it returning the valid ssl ? also send output for the command: openssl s_client -showcerts -connect mail.example.com:465 replace mail.example.com with your valid sub domain
January 4, 20241 yr Author certificate error Message sending failed. The other party's certificate has expired. The configuration related to mail.myclient.com needs to be fixed.

The configuration related to mail.myclient.com needs to be fixed. you can reinstall the ssl from cwp autossl module by deleting the current ssl and then recreating it, this will fix the mail ssl issue
January 4, 20241 yr Author I deleted the certificate and installed it again and the same message appears in thunderbird that does not deliver the certificate add the following command in the terminal and if it gives me valid SSL openssl s_client -showcerts -connect mail.example.com:465
January 4, 20241 yr Try to rebuild the mail server and test also send some screenshot of the error or send the subdomain name for the checks.
January 4, 20241 yr Author Solution now everything works fine What I did, I changed the port to 587 and then went back to 465 and it worked. thank you very much Sandeep B.
