Just f@rting around, I tried using Trend's eManager and hit a gotcha because
we host some listservs inside our firewall.
Outside addressees:
Listserver->Outbound IMS->Firewall-> addressee
outside addressees pass through the firewall and the message is delivered.
Inside addressees:
Listserver->Outbound IMS-> Firewall->bounces back to eManager(poof)
Inside addressees , the firewall bounces the message back to the Trend box
where it's dropped :(
If both IMS's were inbound/outbound, my guess is this would work, but I'm
thinking there's a few more things to think about- like having to create a
rule for each one of 60+ domains, and I haven't thought about it to know
what else yet.
Sure not gonna fool with it on a Friday afternoon, but later...
Paul

One could install an SMTP gateway application which refused inbound SMTP
mail FROM your domain.
