Hello,
I’m trying to set up mail on my server with Enhance, but I’m running into an issue with Dovecot.

i have mails in queue but it's not being delivered to roundcube
this is my postfix master.cf and main.cf

Does Enhance automatically configure and manage Dovecot, or do I need to manually create the dovecot.conf?

If Enhance should manage this, what’s the correct way to enable or reinstall Dovecot so it runs properly with Postfix and Roundcube?

Any guidance would be greatly appreciated.

Thanks,
