Don't know if that says anything new. I would wonder if it's some sort of lookup based on "ctladdr", but I get the same error if use "-f [EMAIL PROTECTED]" which does show up in that field.
sendmail -q -v reports:

You're not even getting the SMTP banner there. I suspect it's
probably something to do with an administrative descision on behalf of
UMD admins -- perhaps they reject connections to hosts in DUL block
lists.
I'll give a shot at changing my domain name - what should I use? I'm a
bit too poor to actually buy one :) Should I just change to use my ISP's
domain?
Yes -- do a reverse lookup on your IP number and use that name in your sendmail config. It may not look pretty, but it should let you see if that is the problem.
The other thing to do is forward all of your e-mail via your ISP's smart host. As you are probably expected to do.
Cheers,
Matthew

Well, I tried forwarding to my "Smart relay host" and get the same error message, with "via relay..." appended. On the other hand, a reverse DNS lookup doesn't work - perhaps this is my entire problem? I'm not sure how to fix it if so!
Here's some output:
aleph# ifconfig rl0 rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::2e0:4cff:fe98:36fa%rl0 prefixlen 64 scopeid 0x1 inet 192.168.0.197 netmask 0xffffff00 broadcast 192.168.0.255 ether 00:e0:4c:98:36:fa media: Ethernet autoselect (100baseTX <full-duplex>) status: active aleph# nslookup 192.168.0.197 Server: ns1.dc.cox.net Address: 68.100.16.30

I do have an entry in my /etc/hosts file: 192.168.0.197 aleph.cox.net aleph
But apparently it's not reading that. [the change to cox.net is just 5 minutes old, BTW].
Thanks again for the help!
Hi Justin...
Matthew meant "do a reverse lookup on your *public* IP number". (As you probably know, 192.168.x.x is an RFC 1918 private [non-routable] network address.) You can use nslookup for this, but supposedly it is (or is becoming) deprecated in favor of dig(1).
However, I'm lazy, and just use host(1). :-D
Based on your last email, I'm thinking you're at 129.2.56.21, which is archimedes.math.umd.edu....
But that doesn't agree with what you've written. What's the output of ifconfig?
