Re: Communications Problem

I wonder who is sending you the message?  It sounds like it is coming 
from partner400.com, not Bell South?

I use mail relay regularly to send mail from my account (martinvt.com) 
which is hosted by pair.com.  pair.com requires that i get mail before I 
send mail, and allows me to get mail for 15 minutes after I receive 
mail.  This isn't a problem as I check for mail every 10 minutes, so the 
15 minutes never elapses.  Apparently this requirement to get mail first 
is enough to discourage most relay spammers.

Anyway, I guess my point is that the problem may not be what you think 
it is.
