Comment:

 I'm not exactly sure what to do about the lack of DKIM. Given bugs like
 #12089, one could easily claim to be from any riseup.net address, and
 essentially send spam (in the form of unsolicited BridgeDB responses) to
 the riseup.net address they spoofed.

 I spoke with the Riseup birds earlier, asking about their DKIM setup:

 {{{
 06:42     isis ) micah: is there any chance that i might convince the
 riseup
                  birds to implement/install/enable DKIM signing for
 outgoing
                  emails from @riseup.net?
 06:43     isis ) micah: (re:
 https://trac.torproject.org/projects/tor/ticket/11139)
                  it kind of got stalled for a while
 06:57 @taggart ) isis: we do dkim
 06:58     isis ) oh? super!
 06:58 @taggart ) but......
 06:58     isis ) though no DKIM appeared when i tested
 06:59 @taggart ) in our dkim record we don't require that riseup.net email
                  be sent by any particular IPs
 06:59     isis ) i tested it by sending through my @riseup.net account
 with
                  msmtp, so it wouldn't have been an IP whitelist stopping
                  the signature
 07:00     isis ) though i suspected that it was because i didn't use the
                  web interface like a normal person
 07:00 @taggart ) we add DKIM headers to lists.riseup.net mail
 07:01     isis ) hmm... would it be possible to add it for authenticated
                  users' outgoing emails?
 07:01     isis ) let me test this from the web interface...
 07:01 @taggart ) and we publish dkim dns records for both lists.riseup.net
                  and riseup.net
 07:06 @taggart ) oh wait I am getting partially mixed up with SPF
 07:06 @taggart ) our SPF records don't specify IPs
 07:08 @taggart ) isis: I didn't set it up originally and it's late, but I
 will
                  talk with others about it tomorrow
 07:08     isis ) if DKIM is supposed to be enabled for individual riseup
                  user's mail accounts, something appears to be broken
 somewhere:
                  https://pastebin.mozilla.org/5434253
 07:08     isis ) that is what bridges.torproject.org is receiving ^^
 07:09     isis ) taggart: okay, thanks!
 07:09     isis ) if help is needed anywhere or you want me to test things,
 feel
                  free to ping :)
