Unless a blacklist adds victims by AS number, a change of MTA's IP (hence the hosting) and an appropriate DNS reconfiguration is sufficient to sidestep it. Of course, one can get an already blacklisted IP, so a certain amount of "hope and pray" applies here. > > With all it's disadvantages, SMTP is one of the few examples of > > successful federated (i.e. - non-centralized) form of Internet > > communications.

A small email domain isn't a big deal to manage or it is? I saw no unsolvable problems in doing it so far, hence my interest to your statements. And yes, I do not consider myself an expert in all things related to SNMP, MTAs and the like. Reco
