as you can see on the subject I need to do the mail processing entirely on an external server. Has anyone ever done this? What do I have to do to make OpenEMM send out the mails via SMTP ServerB? I think, I can figure out myself how to feed the bounces back from ServerB to OpenEMM but the OpenEMM sending mechanism appears to be pretty opaque to me.

If someone here ever did this, I's appreciate all hints or links!
thank you.
