[vps-mail] unknown user question

[Chris Edwards <chris.edwards@xxxxxxxxxx>]

I have a client that had his email rejected because of a 550 error.  I'm 
trying to figure out why.  I've included some log and stats. I've tried 
 testing to see if the email address exists and it seems so. Would 
anyone like to enlighten me?  Thanks.
