There is really nothing I can do about this.

The problem is that GMAIL has extremely restrictive rate limiting. It
really is insufficient for absorbing the rate at which postings are
made on the lists during the busiest times of the day. And when the
rate it exceeded, the gmail accounts in question simply drop postings
for a certain period of time.

So I have to intentionally back off the rate at which
queues up to GMAIL accounts.

If I let it go at full speed then half of the postings would get
dropped and people would miss content.

Complain to GMAIL if you dislike this but I have tried in the past and
they have no intention of increasing their default posting rate
