[plug] [OT] big email delays?

Nope; it's only incoming mail that's being delayed. Nobody's reported 
delay notifications etc, it just seems to be that some mail is "waiting 
in the void". There's nothing in our logs to indicate that we're 
bouncing or delaying mail, and all the postmaster box contains is 
badly-made spam.

In other words, everything looks dead normal from here - yet we have a 
lot of clients reporting that they sent mail hours ago, or even 
yesterday, and it hasn't been received. I haven't had any delays or 
abnormalities in test messages, our MX looks alright, etc. It's just weird.
