Can send mail but cannot receive

Hi
I have issues with receiving email for my domain mydomain.com From postfix mail log, i can see the the received mail had been removed by queue manager but could not find its final destination in roundcube and there is no error log for roundcube. I have compiled mail server with AntiSpam/AntiVirus (recommended), rDNS Check (recommended):  and Install DKIM & SPF (recommended): options.

Does it related to the 'permission denied' error ? I have checked the permission of the /etc/dovecot folder and it looks correct.

Hi

Brris

I have the same problem any solution for it ?

Hi Dear all, I have Same problem please help me

Invalid hostname.
You should not have domain name as the hostname.
Another basic error, which isn't a CWP problem.
