[Discuss] DMARC issue, Yahoo and beyond

[John Abreau]

More precisely, I installed Mailman 2.1.18 in parallel with the older
Mailman 2.1.12, so that both coexist on the server, and I created a sample
list under 2.1.18 for Jerry to test with.

All the production lists are still running under 2.1.12. We won't begin
migrating them to the 2.1.18 instance until after Jerry completes his tests
and we review the results.

Jerry mentioned he was going on vacation this week, and won't be back until
next Tuesday.  I assume this means he'll be deferring the testing process
until he returns.
