I currently manage a windows based mail server for a few small local non-profits and was wanting to migrate them to another (actively updated and supported) mail solution. The community edition has almost everything we need, except that I would have to start managing users myself. The only thing I wasn't able to find was information on a mailbag server. I have mx2.mydomain.com set as a mailbag for the domains, then forwards to the main server when it comes online or delivery threads are released. It doesn't do any spam/verification/dnsbl/etc. All that is done on the main server. The mailbag only has geoip blocking setup since we only receive email from Canada and the US. Will a mailbag server work with zimbra? any limitations?
