SMPT to smart host connection dropped

[Carlos]

Hi,
I have a Win2003 SP1 + Excchange 2003 SP2 Org and a exchange 5.5 Org as part
of a migration.

I set a SMTP connector from 2003 to 5.5 for all SMTP email i.e. a smart
host.

On the 5.5 I have added on IMS routing tab the subnet of 2003 exchange.

All was working fine sending and recieving email from the internet. Now all
SMTP mail is being queued on the 2003 server.

In comming email is OK.

From the SMTP log on 2003 it looks like the odd email is going out. This has
only been happening for a few days. If I reboot the server all mail is sent
and received.

Any ideas??

Users are also getting this email:
......
Subject: Delivery Status Notification (Delay)
Attachments: ATT85365.txt; test from 2003

This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
.......

I can ping by IP and telnet to thw 5.5 server and send email from the 2003
exch server,

You said it looks like the "odd" or "old" email is going out. When
messages are getting queued, you can telnet to this server and send
mail? If so, give this a shot:
