We are running RT and RTIR with Postfix.
Our inbound mail routing is perfect, however we have created a smart relay host in Postfix to send email back to Exchange, however this does not seem to work natively with RT’s mail sending function.
Note: All testing to relay email through the server to Exchange is working.
From a config viewpoint, it seems RT relies on Sendmail to send email outbound.
Is there any options to use Postfix and what arguments should be supplied?
Any feedback or suggestions are welcomed.
