The SMTP port should be blocked! This may cause a little discomfort for a small percentage of the users (I would guestimate less than 5%), but the zombie spam (which is the prime way to send out unsolicited email these days) would decrease radically. Of course those 5% can also be kept relatively happy by providing an easy mean to add exceptions to the filter (as suggested in the post).

Finally, for companies there are alternative solutions which are guaranteed to work (almost) every time, like webmail over HTTPS or a VPN over port 80.

I’ve left ISPs in the past for the sole reason that they filtered and/or blocked port 25 inbound and outbound to anyone but them. That’s big enough to me to be a dealbreaker.

I don’t even know what my ISP’s mail servers and accounts are, since I don’t use them at all and really don’t want to.
