[tor-relays] DMARC helps prevent Tor-exit from being abused for email SPAM.

[boldsuck]

Hi @all,

I thought DMARC was unimportant for a small domain, but I played around with 
it a few days ago.
There are some DMARC monitor sites that you can use for free & I was surprised 
when I saw that in 2-3 days about 1500 emails were sent via my exit 
subdomains.

Then I set DKIM and SPF to strict
adkim=s; aspf=s;
and DMARC subdomain policy  to reject
sp=reject;

Since then, emails about Tor-exits have dropped to 0
;-)
