Hello,

Mail to some of my users is getting sent to the postmaster account
instead.  The only change that has happened recently is replacing the
exchange server.  Otherwise, incoming and outgoing email is working
fine.

Here's the situation, I added a new SMTP address to an account in
Exchange.  ASSP sits in front of Exchange and does LDAP lookups in
Active directory.  LDAP lookups are working okay, I can see them in the
logs and the ldaplist file is populated.

So, say I added an smtp address "[email protected]" - if I telnet to port
25 directly on the exchange server, the user is accepted:
Thu, 4 Feb 2010 15:18:52 -0800
>helo test
250 domain.com Hello [test]
>mail from: [email protected]
250 2.1.0 [email protected] OK
>rcpt to: [email protected]
250 2.1.5 [email protected]

However, if I telnet to port 25 of our outside domain, this happens:
Thu, 4 Feb 2010 15:18:52 -0800
>helo test
250 domain.com Hello [test]
>mail from: [email protected]
250 2.1.0 [email protected] OK
>rcpt to: [email protected]
250 2.1.5 [email protected]

The sender doesn't get any error message, the email is just delivered to
the postmaster account.  This ASSP server has been up for 9 months
without trouble until I recently had to reinstall Exchange.  ASSP
version 1.5.1.4

Any ideas?

Thanks,
Jim
