Thanks Mathias and all the others kind enough to reply to this thread. I think I am now "bottom posing" and quoting properly lol. Anyway couple more questions: a) From what I am gathering the consensus is that Courier IMAP is easier to setup but one benefit to Cyrus is shared mailboxes. Are there any more issues worth considering? b) I am guessing that kernel raid is just as good if not better than the cheapo "fakeraid" cards right? That being said will I get any better performance (yes I know better for space) with sw RAID 5 vs 1? c) I assume that both webfront ends have the ability to setup server side "out of office" replys? d) Now heres maybe a tough one... has anyone played with trying to build a TSL 3.x high availablity mail server? I wander what options there might be? Thanks again guys! _______________________________________________ tsl-discuss mailing list [email protected] http://lists.trustix.org/mailman/listinfo/tsl-discuss
