I am getting the following error message back when I try to send to  personsname@strategicplacements.com.

I cannot find anything wrrong with our exchange server (part of SBS 2003)

After reading certain posts I am getting the impresssion that the error is with strategicplacements.com's mail servers. Is this correct?

This is generally a recipient side issue unless you're sending to huge numbers of users or such where the header size might be too large.

Yes that site is one that i saw that indicated so.

You say "generally". In what situation would it not be their fault?

The error is just a timeout, doesn't really say much more. Could be any number of reasons why the message is failing, including many that are out of your control. Does all email fail to that domain? Can you telnet to their MX record hosts and get a response?

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

what was the error? can't connect? if you can ping by hostename but not connect then a few things are possible:
1. your client anti virus software is blocking port 25 so you can't test (common).
2. there's a firewall or something blocking port 25 between the client you are testing on and the server (depending on security at your facility it's possible).
3. The server isn't listening on the IP resoved by the hostname used, potential reasons: just not listening on all interfaces or the interface registered, multiple IP addresses registered for the hostname, one of which is not accessable from your client. or configuration issue.

perform a netstat -an >netstat.txt on the server, read the netstat.txt file to see which ip it's listening on for port 25, if you see 0.0.0.0 then it's listening on all interfaces.

Was that a telnet to their MX record host? If it just sits there then your client cannot make the connection. If it is only happening with some domains then it could be a routing problem.

See if you can tracert to the same host name and see if the packets die before they should. Ping isn't really helpful as that doesn't really prove anything and many sites will not respond to a ping.

The server is listening on 0.0.0.0 : 25

The tracert to the ip address corresponding to the mx record works fine.

Any other suggestions guys?

If you cannot telnet then the connection is being blocked somewhere. if you can telnet to other hosts (which verifies that everything is working correctly) then the problem must be with the remote side somewhere and you would need to ask them if they are blocking your connection. It could be a connection blacklist for example.
