[Mailman-Users] Part of moderated mails postponed to later digests

One of my list administrators complains that digest mails now seems to be sent in fragmented chunks and instead of sending all moderated mails in a digest the same day, only some of the mails will be sent with a digest the same day, and the rest will be sent in a digest with the next moderated mails, half a week later. For instance, when moderating say 50 mails in week 1 and 50 mails in week 2, the digest mail in week 1 will contain say 30 mails in a digest, while the digest in week 2 will contain like 20 mails from week 1 and like 10 mails from week 2.

There is no information about when the admin discovered the problem, but on August 20th 2015 Mailman has been upgraded from 3:2.1.12-18.el6 to 3:2.1.12-25.el6 and I wonder if the DMARC implementation in 3:2.1.12-22.el6 has something to do with it, as this is the only changes I can think of having any effect on the mail behavior.

dmarc_quarantine_moderation_action is set to Yes on the list in particular and according to some discussions on the Internet, this strict action has been coursing bounces, so I suggested him to set this to No.

But even being strict, I don't see why this would course parts of the digest being held half a week, so something else must interfere.
