This message keeps appearing in the event logs of the exchange server which is running within Windows 2003 SBS

Event ID 3005
A non-delivery report with a status code of 4.4.6 was generated for recipient rfc822; XXXX@XXXXX.COM (Message-ID <1fca501c827c4$45f1ffe0$0203a8c0@pc1>).
Cause: The maximum hop count was exceeded for this message. This non-delivery report can also be caused if a looping condition exists between sending and receiving servers that are not in the same Exchange organization. In this situation, the message bounces back and forth until the hop count is exceeded. A configuration error in the e-mail system can also cause the message to bounce between two servers or to be forwarded between two recipients.
Solution: The maximum hop count is a property set on each virtual server and you can manually override it. The default maximum hop count is 15. Also, check for any situations that might cause loops between servers.

It cannot be the hop count that is at fault unless it took more than 50 hops because I gradually increased the allowed hop count from 15

How do I check whether the mail is being bounced between two servers or forwarded between two recipients, please?

Which settings should I look at and where do I find these settings
Any information that you can provide will be most gratefully recieved and appreciated. Thank you, in advance for any help

ps

Also, there are other errors recorded in the event logs so, if you believe it would help, then I can provide details of those too.

You might want to start with checking the SMTP protocol logs (if you have
protocol logging enabled) this should tell you exactly want is passing to
and from your server
