Sendmail/Exim and IP-Address

[Gary Nichols]

Roderick,

You should test and make sure that incoming tcp/25 is not blocked and does 
not violate your TOS agreement.  Most consumer-level services are now 
blocking incoming SMTP to prevent people from setting up unauthorized 
relays and spam farms.
Not to mention that if you violate your TOS your provider can always pull 
your plug (as a few on this list have experienced in the past).
