[plug] [OT] big email delays?

I'm getting a heck of a lot - 900 messages in the Postmaster mailbox 
this morning :-( and my junk box was well above average too. Still, I 
haven't heard of any ISPs being overloaded, whirlpool hasn't mentioned 
anything, the iiNet netstatus list hasn't said anything about mail 
faults, etc.

Nonetheless, this seems rather odd, and I can't see how any issue could 
possibly be at this end.

Mail from [plug] etc is nearly instant, as usual, for me. Nonetheless, 
I'm getting reports from users of messages sent yesterday that still 
haven't arrived - a few is not too strange, but we're talking lots. 
There's no apparent pattern to it, either. Something funny seems to be 
going on, and mail server trouble at a few big ISPs seems a likely 
explanation.
