Exchange SMTP email not getting to recipients

Hi all,

We are having a major problem getting our email to our recipients.  We are running Exchange 2003 on SBS 2003 and send email through smtp.btconnect.com .  I have monitored the client PC's and the Exchange queue and the email leaves both.
My question is, could this be anything server related i.e DNS or is it more likely to be an issue with BT?  I am able to send email fine from my office via the smtp.btconnect.com server.

Check the message tracking in exchange. You should be able to see whether or not your mails were accepted by smtp.btconnect.com. Then you know if it is your problem (usually DNS or authentication) or a problem with BT.

Do you get any NDR's for these mails?
Can you resolve the mail domain that you are sending to with telnet

Thanks very much, I used MTC and confirmed it was a BT problem.
