On the off chance that your decision to turn off greylisting was
related to Matus Uhlar's message that concludes with:
"if you run SA, there's no point in running greylisting anymore."
That could be interpreted to read "if you run SA at all, there's no
need for greylisting at all", but I don't think that's what he meant.
I think the correct interpretation (at least the one that makes sense
to me) is "during processing of mail, it makes no sense to run
greylisting after SA does its thing".
I had the same thought but I didn't say anything.
I would generalize that even more to say that greylisting should come
before any other content-based filtering (virus scanners, defanging,
etc.).
Greylisting means *you don't see the content at all during the delay*. You
tell the sending MTA to try again later when they first connect and send
the MAIL FROM and RCPT TO. If you implement the delay *after* you've
already received the content, then you're totally missing the point of
greylisting.
On the other hand, you may have disabled greylisting because you're
tired of futzing with it and just want your mail to work right again,
in which case, nevermind.
