I'm running a perfect server on CentOS 6. I started using a mailbox I set up a long time ago and found out it's not working. Everything seems ok within ISPConfig. I'm not sure where to start troubleshooting this. Code: postfix/trivial-rewrite: warning: do not list domain mydomainhere.com in BOTH mydestination and virtual_mailbox_domains This is currently the only mailbox on this domain, all other domains/emails are working perfectly.
