IIS SMTP to Exchange 2003
|
|
|
| I'm trying to send CDO messages from IIS5 (.asp page) to an Exchange 2003 sp1
server. I can send mail via telnet and via Outlook Express from the IIS
server to the Exchange server without problem. My SMTP log shows the
following:
OutboundConnectionResponse -
220+.xxx. com+Microsoft+ESMTP+MAIL+Service,+Versio
n:+6.0.3790. 1830+ready+at++Mon,+13+Nov+2006+18:38:54
+-0500+ 0 0 121
OutboundConnectionCommand EHLO xxx-apps1.xxx.com 0 0 4
OutboundConnectionResponse - 250-.xxx.com+Hello+[10.10.100.54] 0 0 46
OutboundConnectionCommand MAIL FROM:<user@xxx.com>+SIZE=692 0 0 4
OutboundConnectionResponse - 250+2.1.0+user@xxx.com....Sender+OK 0 0 37
OutboundConnectionCommand RCPT TO:<user@xxx.com> 0 0 4
OutboundConnectionResponse - 250+2.1.5+user@xxx.com+ 0 0 38
OutboundConnectionCommand BDAT 692+LAST 0 0 4
The message is never delivered, but the Exchange server delivers the
following message after the timeout period to the sender address (which is
the same as the receiver address):
Your mail message could not be delivered, or may have encountered some
trouble in the delivery process.
I've looked for hours online and tried changing numerous settings without
luck. Any suggestions? Many, many thanks in advance.

| I was finally able to get messages to go through by telling SMTP to not try
to directly send the message first. The smart host is the same address as
where I was sending to so I'm not sure why it matters. I also added in
127.0.0.1 as an allowed relay so that may have also contributed to my success.
