Mike,

I've temporarily stopped using mutt/exim since I can't rely on it to
send messages. Right now I'm using a webmail account from fastmail.

There's no paniclog, but pieces of mainlog are given elsewhere in this  
e-mail.

mnemosyne. I sent e-mail to a domain that almost always accepts my
e-mail (tricity.wsu.edu). Here are the full headers from the message
as received there. This message was sent with exim configured to relay
e-mail through mail.pacbell.net:

That command doesn't return anything, so I'm guessing my IP is fairly   
static. I browsed a few of the /var/log/messages* files by hand with    
less and used /IP to look for anything related -- nothing..

It gets sent, but UCD rejects it for a fairly obvious reason:

(from exim's logs)
2003-04-16 14:11:37 195uBn-0000oX-00 ** jamcp@ucdavis.edu R=lookuphost

No errors given. The logs look like this for one of my 
successful messages:

2003-04-16 14:03:22 195u3u-0000nw-00 <= jam@mnemosyne U=jam P=local S=611
id=20030416210321.GB3083@mnemosyne

2003-04-16 14:03:22 195u3u-0000nw-00 Completed

and here's one for a failed message:

2003-04-16 14:01:29 195u25-0000no-00 <= jam@mnemosyne U=jam P=local S=586

2003-04-16 14:01:30 195u25-0000no-00 Completed

No differences I can see except the e-mail address I'm sending to.

Yep ... I have been. (-:

After the above, I'm starting to suspect that reason my messages are
being rejected is that my hostname (mnemosyne) is local and doesn't
resolve in the outside world.

So, my questions:

(1) What should I set the "visible mail name of my system" to in
    eximconfig? My IP address? the name of my ISP's mail server? If the
    former, how do I keep it updated when my DSL switches IP's?

(2) Do I also need to use the "hostname = ..." setting in my
    muttrc? If so, what do I set that to? (I've noticed that
    setting the hostname in muttrc makes a difference in the exim
    log files... "id=20030416210129.GA3083@mnemosyne" becomes
    "id=20030416210129.GA3083@mail.pacbell.net" for instance.

Jonathan.
