Good to have you back...

I'd agree with that suspicion; I like Scott's mention of external influences
like firewalls; I'd be interested to think about "What's changed?", assuming
that you didn't have this problem with the system (say) 3 months ago. In that
case, have you changed anything about the server or the environment it's in
that might help pinpoint the cause? Also, you say you're seeing this from
multiple senders, but are you seeing this from _all_ senders or is some mail
delivered okay? If some mail is delivered okay, could it be that mail from
particular IP addresses is always delivered okay or always fails?
