Docs Mailing List Delivery Issues

Web Team,

For a long time now many of the emails posted to the -docs mailing list, which do show up in the archive, do not get sent to me even though I am a subscriber to that list.  I do get some, but not all, and rarely the original email.

Specifically, today, I received the first reply, sent by Michael:

https://www.postgresql.org/message-id/20200803074904.GO3317%40paquier.xyz 

But neither the original posting:

nor Tom's response to Michael's post:

This is the only list where I have noticed this inconsistent delivery.
