[miles]> ok I explain <[miles]> we have a transport_maps = hash:/etc/postfix/transport <[miles]> which simply has <[miles]> user@domain1.com smtp:10.11.12.13 <[miles]> domain1.com being a virtual domain <[miles]> user, does not exist in the system, and needs to be forward to 10.11.12.13 <[miles]> the fqdn of the server is say abc.defghi.com <[miles]> when a mail arrives for user@domain1.com , it does get forwarded to 10.11.12.13 <[miles]> however, it arrives as <[miles]> user@abc.defghi.com <[miles]> and it says in the bound <[miles]> (expanded from ) * Anders_l_ has quit (Read error: 110 (Connection timed out)) <[miles]> anyone got any ideas please, this is driving me crazy as now
