Bounced Incoming Email

What's the best way to troubleshoot a problem where outside email from a specific address is not reaching an Exchange 5.5 server? I'm new at this and am looking for some fundamental steps to go thru to track this problem down to it's cause.
Thanksfor any help.

First off, you need to increase your diagnostic logging for the IMC, at a minimum you want message transfer and smtp interface at maximum. This will track your connections and messages inbound/outbound in the Applications Log.

That is one way to track problems. The other for this is to try and traceroute to the mail server in question that can not send to you. There may be network congestion, some of the routers do not have the proper routes. I have personally seen this, where I could not traceroute to a server from our main internet point, but from another point across the country I could traceroute there.

The diagnostic logging would be the best way to track problems of this nature, or contacting the site in question, to see ifthey know of why mail isn't getting to your site.

Hope this helps.

What mebudman@home.com said is correct.
I just want to add some information. You might disg via the DNS as well. NSLOOKUP will be very useful. Do check for the MX and the Host record. Then you can use tracert or trace route for the troubleshooting.

Have a try
Cheers!
