My first time with this. I got postfix, mysql, and postfixadmin setup, generally following http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMailServer I used postfixadmin to create my domain then added my first user and got an error: 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 (faxit at test.htt-consult.com) There is nothing under /home/vmail (in postfix/main.cf: virtual_mailbox_base = /home/vmail) Advise on where to start troubleshooting? Perhaps a password or permissions not right?
