Look at it this way: If it was open by default, a lot of IPs would be blacklisted, making them basically unusable for email anyway.&lt;p&gt;You can always rent a subnet or a server including network and host mail yourself.</text><parent_chain><item><author>jaytaylor</author><text>Blocking port 25 is pretty annoying.

You may not have a public IP, and if you do, it likely changes from time to time.
