[Mailman-Users] More mass unsubscriptions

[Lindsay Haisley]

This morning at 9 AM CDT one of FMP's lists here saw another mass
unsubscription event - 51 subscribers with the usual ESP addresses:
hotmail, yahoo, comcast, bellsouth, etc.  Checking the list archive,
there have been no posts to the list from yahoo.com since the 13th.

Someone else must be publishing a DMARC p=reject record.  Any insight on
this?  

I've told the list admins that putting all yahoo.com subscribers on
moderation so that they can read list traffic but not post would put a
band-aid on the problem, but apparently this isn't the case.

Is there a delay inherent in Mailman's bounce processing that would
cause the unsubscriptions today rather than on the 13th when the last
yahoo.com post was received by the list?  Posts that have come to the
list today are from:

osu.edu
sbcglobal.net
cyberport.net
