I don't do that for a host of reasons. Not least of which is that it is
just as easy for the remote admin to fix their server. If you add the
server to a white list, then the users concerned have no motive to work on
the remote administrator to fix the server. Then, when the start sending
mail to my server, I have a hard time convincing them to fix their server.
The remote admin will say, "but this other remote site made an exception
for me", so I have to say, "how many remote sites to you want to persuade
to whitelist you".
I can list a dozen schools, a University, and several academic professional
organisations that I've persuaded to fix their servers, so you don't have
to whitelist them.
