This is on Centos 6.3, using 'stock' postfix, mysql, dovecot, and roundcubemail; following (pretty much) the tutorial at
So I am up to trying out the system, and used postfixadmin to create the domain the server is in, then a user and got an eror:
Send Welcome mail: yes
Unable to send email!
The mailbox has been added to the mailbox table, but none (or only some) of the predefined sub-folders could be created
There is nothing under /home/vmail (in postfix/main.cf: virtual_mailbox_base = /home/vmail)
OK. Got this figured out. Firewall and Selinux blocking. Firewall for the needed ports was easy. For now Selinux in permissive mode as I read the howtos on it.
Adding a user is very slow. Seems to be problems with my postfix setupMore research.
