Problems w/ Exchange 5.5 MTA

Tech-Archive recommends: Fix windows errors by optimizing your registry

I am having some problems with my Exchange 5.5 MTA. Here is the
configuration.

Antivirus is configured correctly.
Exchange 5.5 SP4
Windows 2000 SP4
This server is a bridgehead with Directory Replication Connectors, Site
Connectors and an Internet Mail Connectors.

Recently, users have been complaining about mail not going to their
intended recipients. I created some test accounts on various servers
and noticed that some mail made it, some did not. When I track the
messages, they typically get received by the MTA but do not get
forwarded on to a connector or another MTA. They just disapear.

Any suggestions as to why some go but others do not.

I have run MTACHECK......
