Another call for MS Exchange 2000 clue
OK, I did some more work today and I've narrowed it down. Unfortunately my Google-fu is failing me tonight - I keep finding other people asking about the same problem, but no solutions.

I found out how to get more logging, and this is what I get on the 'Secure' virtual host:
---
Event Type: Warning
Event Source: MSExchangeTransport
Event Category: SMTP Protocol
Event ID: 1710
Date: 4/24/2006
Time: 9:17:54 PM
User: N/A
Computer: MAIL
Description:
The SMTP client "10.0.0.41" authenticated as user "CYPHERMINT\fubar" attempted to send as "fubar@cyphermint.com". Access was denied because the authenticated client does not have permission to Send As this SMTP address.
Data:
0000: 05 00 07 80 ...€

Of course, the email address for a user 'fubar' in the domain 'CYPHERMINT' *is* 'fubar@cyphermint.com'. So it is saying, basically, 'this person can't email as themselves'. So it seems the virtual server has some disconnect - not realizing that CYPHERMINT\fubar and fubar@cyphermint.com are one and the same.

Now, this is what the 'Default' virtual server logs:
---
Event Type: Information
Event Source: MSExchangeTransport
Event Category: SMTP Protocol
Event ID: 1708
Date: 4/24/2006
Time: 9:02:53 PM
User: N/A
Computer: MAIL
Description:
SMTP Authentication was performed successfully with client "[10.0.0.41]". The authentication method was "NTLM" and the username was "CYPHERMINT\fubar".
---

So it seems to be fine.

I'm guessing it is something in Exchange, or maybe Active Directory, that needs to be set to make the new SMTP server recognize the relationship like the old one does.

So, any clue is appreciated.

Well, I'm more of a UNIX guy, ymself, but the way I'm rading that error message, it's not the user ("CYPHERMINT\fubar") that's the problem, it's the client (10.0.0.41). I don't know if exchange has settings for something like 'allow relay from'. It probably does, but I have even less idea WHERE.

Yeah, that's what I was thinking - but in my testing I added all the relay rules from the Default server to the Secure server and it didn't help. *And* the Secure server is set to allow any authenticated client to relay anyway.

The Authentication itself is working fine - but then the server says "Oh, user Fubar in domain Cyphermint isn't allowed to 'send as' fubar@cyphermint.com" - and I don't know why that happens. And only on the one virtual server.

Clearly you need to use Sendmail and Cyrus IMAP.

HTH, HAND. 8)
