[IMail Forum] 450 Busy Sending to ATT Addresses

[Jeffery Rehm]

Got one I just can't quite figure out.  When sending to [EMAIL PROTECTED] 
the email will bounce back to the local sender and the logs show a 
couple of things.  First, there's a 450 Busy.  Also will get an 
authentication required, but not everytime.  Happens only with att.net 
addresses.  What is interesting is that even though it shows that 
delivery failed, the receipient will eventually get the message.
