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, [EMAIL PROTECTED]), 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: [EMAIL PROTECTED] becomes [EMAIL PROTECTED] 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: '[EMAIL PROTECTED]" 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.
