I have exim 3, but I tried some of what you suggested.

With debugging on, I see the conversation go like this:

    diderot:~# exim -d  -M 1Bt3Fm-0007Io-00

I've googled a bit on this problem, it's clearly not unique to me, but
I haven't seen any solutions posted online.

I now have one message that has been dropped from the queue and three
sitting in the queue.

I suspect this is spam-related, but I'm not clear how to check if I'm
in any black hole lists (I don't think so, else more would fail) or
what's going on.  Here's a manual check from krypton.cs.drexel.edu:

    jeff@krypton:jeff $ telnet relay.verizon.net smtp
    Trying 206.46.170.12...
    Connected to relay.gte.net.
    Escape character is '^]'.

    250 Ok resetting state
    MAIL FROM:<jeffa@cs.drexel.edu> SIZE=5067
    250 Sender <jeffa@cs.drexel.edu> OK


Any ideas what might be going on or what to do about it?

I just found out today that a different ISP is refusing to *deliver*
mail to me, no reason given.  *Sigh.*
