The problem with distributed mail servers and inbound filtering is that keeping in sync the various filters to avoid a number of issues may be quite a hell; so, in general, people tends to avoid such an approach (that is using multiple MX) and implement some kind of fault tolerant setup using a single MX with multiple IPs leading to different and totally separated connections and pointing to some kind of "cluster" of boxes sharing a common data backend now... it all depends from which level of fault tolerance you want/need to obtain; see, in case of natural events having all the servers into a single room, even if connected to different pipes isn't too much secure so, in such cases you'll need geographically distributed servers and some other countermeasures; in this case you may evaluate setting up multiple copies of ASSP v2, using a backend database (e.g. MySQL) with replication support along with "rsync" for files and then configure the whole thing so that a given "master" server will replicate data and config with all the secondary ones; I know, due to the fact that ASSP works "half & half" (part of the data is stored in flat-files, part in db) this may be a royal PITA, but it works... although it's no faint-heart kind of config ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
