[network-health] Mail from tor relay blocked by Microsoft

[William M Buck]

I run a relay, or I did until yesterday.

I suppose you know about this problem, new for me. Mail from accounts on 
my server addressed to hotmail.com and live.com addresses suddenly 
stopped being delivered. The bounce message from Microsoft claimed I was 
on a block list.

I checked, and the only list I am on is the one run by 
https://www.dan.me.uk/dnsbl called *.tor.dan.me.uk *which reports every 
ip address participating in Tor, including relays. He warns against 
using the list to block mail, but Microsoft seems to be doing it anyway.

As soon as I stopped the relay, mail began to be accepted again within 
an hour or so.

I have had to shut off my relay because people are complaining they 
can't send mail to their friends/relatives on hotmail or live addresses.

This is a difficult dilemma for me. Much as I want to continue to run 
the relay, the people using my mail server aren't going to be agreeable 
to being told they can send mail to friends on hotmail.

I wrote also to the guy, Dan, in the U.K. to tell him his list is being 
used in this way.
