Comment (by epoch):

 Replying to [ticket:10268 epoch]:
 > While trying to get qmail working over tor I found that it will work if
 ALL and MX records don't return NOTIMPL. In the attached patch I have ALL
 records doing whatever A and AAAA records do and MX just returning
 NXDOMAIN. (Which should be fine since MX records aren't required and MTAs
 should fall back to A records if they don't exist, right?)

 Didn't know that descriptions weren't changeable... Right now the patch is
 returning NO ERROR for queries for MX records with 0 answers. Which is
 what seems to be correct according to what bind does when a domain doesn't
 have an MX record and should satisfy the process in
 http://tools.ietf.org/html/rfc5321#section-5.1 describing how mailers
 should figure out where to send mail which says NX returned for an MX
 lookup is supposed to be reported as an error.
