Problems with account

[Leonard Spell]

I am having problems with this account - it doesn't appear that any 
other accounts are having problems.  Does anyone know where I can start 
to troubleshoot this?  I can't find anything in the logs that delivery 
was attempted.  The account [EMAIL PROTECTED] is on my sims server.
