FYI, Our Imail server was being brought to its knees by dictionary attacks. We actually made the problem worse by installing a backup server using Imail. Because they didn't sync accounts, the backup just relayed ALL mail to the Imail server, making the Imail server have to deal with its own dictionary attacks and those from the backup server. We tried using Sandy's ldap2aliases scripts to synchronize the servers but couldn't get it to work after a couple of tries (no reflection on Sandy's scripts, since they work fine elsewhere, they just wouldn't work for us). Unfortunately, those couple of tries caused some havoc in our email system so the higher ups decided that we wouldn't be using that method. No questions. Just find something else.
Finally we installed IMGate and, like magic, the Imail server finally breathed a sigh of relief. It did cause other problems, mostly because we had no idea how many people we and our clients do business with have incorrectly configured mail servers. Again, the higher ups used their infinite wisdom and crystal balls and decided that those people weren't misconfigured, we were. So, we ended up losing the IMGate configs and just going with a basic postfix config that filters dictionary attacks and a couple other things. We left the spam filtering up to Declude. Now here's the rub: Imail server - Quad Xeon 2.4GHz; 1GB RAM; SCSI 15KRPM HD's with separate physical drives (mirrors actually) for system, mailboxes and spool; Windows 2000 Server Postfix server - single p2 300MHz; 196MB RAM; single AGA-100 HD; FreeBSD 5.3 So that powerful Imail server was being brought to its knees until that lowly postfix server rescued it.
