I've been searching for a few hours and still no result...
I'm using a VPS with Debian OS and Parallels Confixx panel installed.
I can see many undelivered emails in my mail.log file, having this kind of error:
Sep 8 15:36:47 vps8713 postfix/error[26333]: E24031F580057: to=, relay=none, delay=17211, delays=17209/0.9/0/0.64, dsn=4.3.0, status=deferred (mail transport unavailable)
When I try to: postqueue -i E24031F580057
a new message in mail.warn file appears:
Sep 8 15:58:03 vps8713 postfix/qmgr[20269]: warning: connect to transport scan: No such file or directory
I'm pretty sure it's because of misconfiguration but no idea anymore. I switched off all the spam filters, assassins, etc. I don't need them, I simply want to have all the mails sent and received.
Here is my main.cf and master.cf files:
