I can't remember having trouble with large emails, but we stopped using Sendmail long ago, and so I don't really know the tools you mentioned except for SpamAssassin and clamav, which we both use. If you have timeouts, maybe looking at some performance indicators helps you to pinpoint it. Eg. there could be DNS timeouts dragging everything to a halt, problems with fetchmail, or the machine simply isn't powerful enough for scanning large amounts of large emails. How many and how large emails do you process per day, and what are the current/prospective machine characteristics? > I don't mind doing the research and figuring out how to make > it all work (although a point in the right direction would > be appreciated). I just would like to know what people are > using that really works for them. We use qmail-ldap + qmail-scanner + SpamAssassin + maybe some virus scanner(s) like clamav or, in the past, TrendMicro. If you have enough horsepower in your machine, this should not be a problem. I'm personally not too fond of qmail-scanner and am looking to (probably) replace it with qpsmtpd once I get enough time to become familiar with it. I'm also considering additional anti-spam engines. You can probably run commercial virii using the Linux emulation if you really want, but from my perspective, punching holes into an application gateway using insecure applications is an endeavour of doubtful merit. You should probably look at sysjail at the same time, to contain these. Best, --Toni++
