Dunno, but it's kinda nasty one of the larger sources of spam demanding 
those forwarding Email to inboxes on their servers have spam filtering 
in place (presumably to eas the load on Comcasts own filters??).

pobox.com is a forwarding service.  You may currently use Comcast as 
your ISP (say) and have the account/Email foobar () comcast com.  But, 
because you've been bouncing around the net for ages and long ago got 
sick of all the hassles of changing all your mailing list, on-line 
newsletter, etc, etc details each time you moved, changed ISP, etc, etc 
you setup an account at pobox.com and use foobar () pobox com as your only 
"public" Email address.  Now, when you move ISP, you simply log into 
your account at pobox.com, change your "real" Email address and 
pobox.com stops forwarding foobar () pobox com's Email to foobar () aol com 
and starts forwarding it to foobar () comcast com.
