Exchange 2003 SP2 Outgoing Emails Stuck in Queue

I have a few emails going to a specific domain (same user) stuck in my outgoing queue. I ran a telnet session to send a manual email to that user. The telnet text is attached.

Can anyone shed some light on why these emails are getting stuck?

Thanks in advance!

Any error in the logs? Any bounce backs?

Hi,

Please check the queue Viewer  to find out error why message is queued:

In Exchange System Manager, dig down through your administrative group / servers / your server name / protocols / smtp / queues.

Only a warning email so far saying the email is delayed.

Subject: Delivery Status Notification (Delay)
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.

In the Exchange System Manager/Servers/SERVERNAME/Queues I can see the 3 messages sitting within the "Internet Mail SMTP Connector (ServerName) - receivingserver.com (SMTP Connector".

The state only says "Queued" but no errors.

If I dig down into the protocols/smtps it just says "default SMTP Virtual Server" and there is nothing listed under "Current Sessions".

Thanks,
Dan

As far as I know it is the only user to attempt to send an email to that domain.

I attempted to send to the same recipient from a different email address and it queued just the same.

Ash I think you are right. But I will wait until the email expires and I get an NDR and see what the error it tells me. Then I will have something to give to tech support for the receiving server.

Thanks,

Yes as I thought, sounds like a problem with the recipients mail server.

Sorry I didn't see that post. I just checked it.

Reverse DNS is setup through our ISP

Our IP is not on any black lists

Our Reputation is neutral

SPF record was not found but a TXT record was (I will look further into this)

Do you want to ping me a test mail and I can run some checks on the info gleamed from my server's anti-spam software?  (Assuming you get past my defences!)

If you do - fire one to testmail@sohomail.co.uk
