By "drop" I mean that I see sendmail log a message in maillog, but nothing
gets sent on to my user account. That message is logged as zero size.

While writing this reply I noticed the `tail -f /var/log/maillog'
(that I have running in another window) scroll and I just saw this:

Jan  2 17:32:27 freebsd1 sendmail[1460]: RAA01460: lost input channel from misery.sdf.com [204.244.210.193]
Jan  2 17:32:27 freebsd1 sendmail[1460]: RAA01460: from=<tom@sdf.com>, size=0, class=0, pri=0, nrcpts=0, proto=SMTP, relay=misery.sdf.com [204.244.210.193]

which displays the same symptoms as the problem from the other relay, except
for the "lost input channel" message. So what did you do to cause that?
Was it a re-transmit from earlier in the day/night?

FWIW, the relay I have problems with is homeworld.cygnus.com which handles
both CVS and mailing lists for NetBSD. Chuckle. I _know_ that it's
configuration hasn't changed because I have an account on the machine.
NetBSD use qmail. I have a .qmail in my home directory that forwards
mail to the same address that FreeBSD sends to. If I send mail from
here to my account on that machine, it should be forwarded back like
it used to. Instead I see:

Jan  2 17:28:15 freebsd1 sendmail[1429]: RAA01429: from=<jb@NetBSD.ORG>, size=0,class=0, pri=0, nrcpts=0, proto=SMTP, relay=homeworld.cygnus.com [205.180.83.70]

which has been trying since yesterday.

So I tried subscribing to one of the same NetBSD lists from that machine,
after deleting the .qmail so that the mail would be saved. Here is the
header from a message saved on homeworld.cygnus.com, that I should have
received as jb@cimlogic.com.au:

Now if I set .qmail to redirect mail to jb@freebsd.org and use the
FreeBSD forwarding (only for a short while 8-) and I send a message to
myself on that machine, I receive the mail OK:

Jan  2 17:57:13 freebsd1 sendmail[1494]: RAA01494: from=<jb@NetBSD.ORG>, size=770, class=0, pri=30770, nrcpts=1, msgid=<19980102065147.20258.qmail@mail.NetBSD.ORG>, proto=ESMTP, relay=y.physics.usyd.edu.au [129.78.129.110]
Jan  2 17:57:13 freebsd1 sendmail[1494]: RAA01494: to=<jb@freebsd1.cimlogic.com.au>, delay=00:00:02, xdelay=00:00:00, mailer=local, stat=Sent

but the *exact* same mail message sent direct to this machine fails
with:

Jan  2 18:00:16 freebsd1 sendmail[1504]: SAA01504: from=<jb@NetBSD.ORG>, size=0, class=0, pri=0, nrcpts=0, proto=SMTP, relay=homeworld.cygnus.com [205.180.83.70]

So must be something wrong with the configuration. But the rewriting
rules haven't changed since 2.2.2 which worked!

I think I'll grab another disk and put 2.2.2 on that and see if it still
works. I'm not sure what else to do. Sigh.
