No header there.
I tried using a default procmailrc ie: not specifying a file in the alias
just to see if that would change the behavior as I was getting an error
message in the maillog about the kind of file the test filer was. I had a
very interesting result sending a test message:
Jan 27 23:16:34 yoda sendmail[32764]: XAA32764: from=<ed@wrenkasky.com>,
size=20679, class=0, pri=50679, nrcpts=1,
msgid=<4.3.2.7.2.20010127231625.00b74728@mail.wrenkasky.com>, proto=ESMTP,
relay=eds.wrenkasky.com [10.0.0.11]
Jan 27 23:16:34 yoda sendmail[32765]: XAA32765: clone XAA32764,
owner=owner-test
Jan 27 23:16:35 yoda demime[300]: One argument required - the relay to
address.
Jan 27 23:16:35 yoda sendmail[305]: XAA00305:
from=owner-test@wrenkasky.com, size=232, class=0, pri=30232, nrcpts=1,
msgid=<200101280716.XAA00305@wrenkasky.com>, relay=majordom@localhost
Jan 27 23:16:35 yoda sendmail[32765]: XAA32765: to="|usr/bin/procmail -f-"
, delay=00:00:01, xdelay=00:00:01, mailer=prog, stat=Sent
Jan 27 23:16:35 yoda sendmail[307]: XAA00305: to=ed@wrenkasky.com,

Jan 27 23:16:35 yoda demime[312]: One argument required - the relay to
address.
and then just kept trying to send over and over until I killed
resend. What's interesting is that demime works fine from the alias when
allowed by the shell. I have no idea why it's saying that it's missing the
relay to address.
