Hi All,

I am having a very strange problem with my SBS2003 SP1 Exchange server component I hope someone can help me with.

This server has been installed for approx 2 years.  I have about 20 user accounts and 25 email addresses routing to those accounts.  Recently, one of those 20 accounts stopped sending email, with the return message: "550 5.7.1 Unable to relay for accountname".  The strange thing is that all accounts on the server can successfully receive messages, and all accounts, except this one, can successfully send messages. 

This single account is the only one having trouble.  It has worked fine for the better part of 2 years, but just started failing about a month ago.  The problem account has domain admin credentials, and nothing should have changed on either the server, or this individual account, except the monthly MS patches.

I am completely lost here, and hope that someone knows what may be happening.  Any help is greatly appreciated!
