I have also error when reloading the second instance fatal: bind 192.168.1.60 port 25: Address already in use but each one of instances has different myhostname ans inet_interfaces settings
> When I try to send mail to account from the second instance I get this error > in mallog where myserver2 is virtual domain in the second postfix instance > > relay=none, delay=13, delays=13/0.03/0/0, dsn=5.4.6, status=bounced (mail > for myserver2.com loops back to myself) Each instance MUST have a unique myhostname setting. Each instance MUST have a unique inet_interfaces address list. Otherwise, the Postfix SMTP client will report "mail loops back to myself" errors. Wietse
