Look hard at DNS resolution... spam filters now do host name checks forward, back, inside, out. A volume email server needs access to a local quick name server. Adding a local name server or moving the local name server to a dedicated machine could be a win. There is no easy way to benchmark a mail server that is in operation. One thing to tinker with is a "fetchmail" benchmark of a known set of messages from some place like gmail. You can watch the mail get processed (mailq), watch the name server and file IO etc. By refilling your INBOX from "All Mail" or a saved folder you should be able to play it again. If you need a pile of spam use a throw away gmail account and almost register for one of those "free laptop offers" that Google pops up. -- NiftyCluster T o m M i t c h e l l
