Note the difference between reject (at the SMTP level) and bounce (which involves composing a new message and submitting it to another MTA). Do you recommend accept and discard instead of reject? I'll admit that this is preferable if the connection is not from the originating MTA, but if it's the spammer or infected machine that's trying to push their stuff at your users, you're better off rejecting it with a 5xx status and not doing any further processing. > Our customers have saved $10,000s or more by not running > anti-virus/anti-spam software on backups. :) It often isn't possible to > use the same rules anyways, if you swap secondaries or pay for a hosted > secondary. I run SpamAssassin on all my servers. More and more ISP's are offering SA as an anti-spam solution so it's not too hard to get secondary service with a comparable class of filtering.
