Re: Communications Problem

["Bob Crothers" <bob2@xxxxxxxxxxxxxx>]

David,

I've seen ISP's who do care about the reply to address.  McLeod USA dialup is 
one
of them.  If your reply to wasn't a McLeod address, you could not relay thru
their servers.  And they had port 25 blocked to anyplace else.

Should they care according to the RFC's?  No.  But some do look at it as a way 
of
spam control.
