I have setup smtp for an application on XP SP3. It can send outgoing to

gmail and yahoo, but when it tries to send to send to our local exchange

2003 sp2 server , message gets stuck in local smtp queue.

When I reboot the XP machine exchange will accept the messages for delivery.

Very odd. at first I thought it was a problem with the XP SMTP, but now I

am looking at the Exchange config.

from XP smtp event log

Message delivery to the remote domain XXXX failed for the following reason:

The connection was dropped by the remote host

My thanks

Can you telnet to port 25 of your Exchange Server from the XP machine?

So when the messages are stuck in the SMTP queue on the XP machine you can

Telnet to port 25 of the Exchange Server? Vice Versa, can you telnet to

Port 25 on the XP machine from the Exchange Server when this happens?

I can telnet to port 25 both ways. I tried restarting the service and the

the queue stays the same.

Only a reboot will empty the queue and send the messages.

it is using ESMTP 6.0 on the problematic XP boxes.

Thanks!!

Update. The problem is just with Exchange. Emails flow out to my gmail

account and to a local Linux box - neither use exchange.

Well, if you can telnet both ways then verify all DNS settings are correct?

I find it very odd that a reboot clears the queues. Its almost as if

something on the XP machine gets loaded on reboot after the SMTP service

gets loaded. This may be the reason the queues are clearing on reboot. I

would suggest by systematically disabling startup services/programs to see

which one is the offender. I would start with firewall or av product on the

XP machine. You can adjust these settings using MSCONFIG from Run Command.

Are you just telnetting or are you telnetting and completing the

entire SMTP transaction? If you were just telnetting to check the

port, complete the entire SMTP transaction it sometimes will give you

a more descriptive error.

Mail goes thru when telnetting in to our exchange server. I followed the

procedure in technet 153119.

could it be the sp3 implementation of smtp on the XP boxes?
