unknow user error in squirrelmail... 550 error

[ssnapier]

I am trying to send mail to a known good address (I own it) and I keep getting this error, any ideas?

Requested action not taken: mailbox unavailable
Server replied: 550 "Unknown User"

the address I am trying to send to is scott (at) vwmail (dot) net

nevermind... I think I found the glitch...

I had setup the vwmail.net domain to be transferred to hostpc, but I have not done it yet. I am guessing that the local servers were confused and unable to send it since I had it sitting here. I deleted the domain in DA and it seems to be working now.
