Okay, I got myself a problem I need some serious help with.
I run various mail servers that run RedHat Linux, and a variety of MTA's
(Postfix, Sendmail namely) and some have Mailman on them. They all work
wonderfully. However where I work we have an Exchange 5.5 server for our
mail, and I've got a problem getting Mailman/Sendmail to work with it.
Every time I send an email to a test list (for example,
test-l at listbox.corporate.net), the Exchange server replies saying "Unknown
User" or "Unknown Receipient". Now I have no clue what is causing this,
aside from the explaination I've been given:
Exchange Server 5.5 strips the "hostname' from the email address:
list at listbox.corporate.net becomes list at corporate.net.
The Listbox is running RedHat 8.0, Sendmail, and MailMan 2.0.13
The full error when I try to send from my corporate account is (I have
blanked out our listserv's domain for security reasons):
Your message did not reach some or all of the intended recipients.
Subject: test
Sent: 4/4/2003 2:23 PM
The following recipient(s) could not be reached:
'test-l at xxxxxxx" on 4/4/2003 2:23 PM
The recipient name is not recognized
The MTS-ID of the original message is: c=us;a= ;p=city of st.
jose;l=STJOSEPHMAIL0304042023210THHRM
MSEXCH:IMS:City of St. Joseph:CITY:STJOSEPHMAIL 0 (000C05A6)
Unknown Recipient
If anyone can help out, it'd be appreciated. I've NEVER had these problems
with Mailman in the past, and I'm of the opinion it's Exchange.
Thanks in advance...
