So, if I understand this correctly, mailman is completely unaware of it's
own IP, even though it is aware of it's domain names?
I need listA to distribute on 22.214.171.124 and listB to distribute on 126.96.36.199.
The reverse isnt really an issue, as once the mail gets to the MTA, it's
effectively at mailman, but I'm trying to wrap my head around a solution
for breaking up the outgoing mail onto separate IPs. if I recall, mailman
IS very much aware of its domain and addresses. isnt this going to cause
issues with rewriting virtualized envelopes?
