Server does not necessarily equal business. A server that handles a few personal mailboxes for a residential user is not 1000lbs of concrete. Offhand, I can think of a lot of uses for various types of servers at a residence that don't require special business features, and are generallly low-traffic. Some people might be a little upset if they brought their brand new leased Camry home, to find their particular dealer had made an ad-hoc decision to weld the trunk shut, and didn't tell them about it directly and immediately, when advertising the vehicle. You want to haul a few groceries home? Shoulda asked for a "business" camry. Nevermind that the manufacturer has no separate product for that, it was a dealer's arbitrary decision to block that particular "port", anticipating customers would otherwise try to do evil things with it (like try to haul concrete). Anyways... like it or not.. blocking of outbound/inbound 25 may be common. But how common was the original question.. not 'is it a good idea?' or not. I would suggest that blocking the destination port 25, outgoing traffic from the end-user's point of view is the more preferred choice, it is more efficient, in that the block is closer to the source, and there are fewer wasted bits of traffic. -- -J
