While that's certainly true, if you've configured SA to scan *before* the DATA phase, I'd be curious to see how well it's working for you. That said, Mark seems to be missing that milters don't have to run pre-DATA to be beneficial. To take another useful example, using ClamAV's milter prevents your mail server from having to accept responsibility for delivery of a virus. But it, too, needs to run post-DATA.
