Hello guys,
I detected a problem in my awesome CWP before changed rDNS.
The .crt file located in /etc/pki/tls/certs/ doesn't rename.
The .key file located in /etc/pki/tls/private/ doesn't rename.
This problem caused dovecot doesn't start. U shall rename this files and restart dovecot manually with this command:
service dovecot restart
For example. If your rDNS see like this: example.domain.com the files renamed to:
/etc/pki/tls/certs/example.domain.com.crt
/etc/pki/tls/private/example.domain.com.key
Sorry for my regular english :S and much thanks for this awesome panel ^^
