Greetings, I am wondering if anyone can direct me to any books/sites/etc regarding possibly running postfix on one or more servers accepting mail, processing with SA, then forwarding onto a 3rd machine.
Currently my setup only includes one Postfix box, which does all of the mail filtering (with spamassassin) then forwards it on to a mailbox holding server. The setup works, however I get so backlogged. For example, running a mailq as we speak, comes up with: 35918 Kbytes in 5257 Requests. It eventually gets through, and during the night it catches up. I am seeing delays up to 3 hours sometimes. I tail -f the maillog file and it's constantly running, so there is definitely activity. Running top indicates 4 main processes with spamd indicating the slowdown is, indeed, with SpamAssassin. I originally thought it might have something to do with the Bayes database, but for fun, I deleted it to see what would happen. Same result. I am running a dual P3 1ghz machine currently and have plans to upgrade that to a dual xeon 3ghz. However, I know this is only a temporary solution and at this point I'm not sure that it's enough. I get an enormous amount of mail coming into this machine and need to plan accordingly for future growth as well. So my goal is to possibly balance the incoming mail between two beefy machines to do the processing, hopefully accomplishing and eliminating this slow down. My question is any suggestions on a different way to do this? Or are there suggestions on accomplishing a more balanced load between two machines. Any comments, helpful hints or suggestions would be more than welcome. Thanks, Alan Fullmer www.xnote.com www.zoobuh.com
