Comment (by gk):

 Alright, I attached the
 [https://trac.torproject.org/projects/tor/attachment/ticket/32672/bug32672_emailed_20200225.txt
 file] containing all the relay operators with relays running obsolete Tor
 versions we want to reject (that's from last week). Additionally, I
 attached another
 [https://trac.torproject.org/projects/tor/attachment/ticket/32672/bug32672_control_20200305.txt
 file] showing the remaining operators on those versions, a bit more than a
 week after the email campaign.

 We can see that the amount got reduced by 1/3 which is encouraging, even
 though I have not made a detailed analysis yet whether the operators
 actually migrated to newer versions or shut them down or... Interestingly,
 though, the sum of the bandwidth shown for the relays in both files
 *rose*. I have not looked as to why this happened.

 Some explanations to the annotations I made on the file I used for sending
 the emails:

 "[x]" means I sent an email successfully.
 "[xf]" means I sent an email but I got an error back.
 "[xfam]" means I sent an email and asked to set `MyFamily` properly while
 I was at it.
 "[f due to $]" means I did not send an email due to $.

 Additionally, you'll see that I changed my strategy for sending mails to
 the operators during the whole process: First, I send the email and Cc'ed
 the network-health list without any `Reply-To` header. Then I did the same
 with `Reply-To` header set to the mailing list. Then I only Cc'ed the list
 with the proper `Reply-To` header if the email address was not obfuscated.
 And then due to complaints by folks subscribed to the list I sent the last
 batch of mails without Cc'ing the network-health.
