[tor-talk] using torbirdy + thunderbird: domains emailing with dmarc

im a little concerned about the following and still trying to figure it out:

if multiple parties are using torbirdy with thunderbird and lets say
some domain owners have dmarc setup with reporting enabled

other dmarc capable domains (gmail, hotmail) will send back reports with
the IP used for mail transmission & respond with fail or pass

essentially you'll see fail every time if you use torbirdy *and* your
domain is configured with dmarc, and its going to leak the IP you sent
email from (logged in with thunderbird to send) defeating the purpose of
using torbirdy

the dmarc queries are going out in the usual clear dns

are there any other shortcomings here that are of concern?

is dmarc reporting too privacy invasive in this situation to bother
implementing, and better left to business/companies ?
