Static relaying to a remote MTA using imta.cnf

Hi,

Pretty straight-forward.

1. Add a new channel in your imta.cnf file which sends off all email queued to it to x.y.z.k e.g.

!

! tcp_static

tcp_static smtp nomx single_sys subdirs 20 dequeue_removeroute maxjobs 7 pool SMTP_POOL daemon x.y.z.k

tcp_static-daemon

2. Add a rewrite rule in your imta.cnf file to direct traffic to the new channel for a domain e.g.

specific.domain.com$E$F$U%$D@tcp_static-daemon

You will need to rebuild/restart the MTA for the change to take affect.

Regards,

Shane.

That should be fine.

You should really do it properly and have the hostname/IP added to your DNS servers if you are going down this path -- shortcuts such as this tend to come back to haunt you in the future (such as you forget to update the /etc/hosts file and spend hours tracking down why email delivery doesn't work).
