moderated Re: A 554 Bounce code not recognized as bouncing on first occurrence #bug #fixed

I would just like to squeeze in some more data to this topic to
show it is not just related to users with special-notice delivery,
as well as other observations.

For me, the bounce code seems to be working.

Transfer of my group from YG to GIO occurred on Thu 2019/11/14.

In 2019 there were 2 occurrences of multiple bounces : 14 Yahoo
email addresses on Fri 2019/11/15, and 118 Yahoo email addresses
on Wed 2019/11/20. Since then, quiet.

Looking at Admin-->Activity logs last week, 10 users started
bouncing as of Jan 30, 2020. These were triggered initially by
messages I posted followed by bounce probes.

Of the 10 users, 9 have email addresses on yahoo.com and 1 has an
email address on yahoo.co.uk. Basically, all Yahoo. Of the 10 users,
6 have Single-Delivery set, and 4 have Full-Digest-Delivery set.
The oldest account is from 2003-07-03 and the newest is from
2018-06-09

Then looking at the Email Delivery History for each user, multiple
entries were seen dating back to Sat 2019-11-16, just 2 days after
my group arrived in GIO. Here is the Email Delivery History for
one such user, the remaining users are the same.

Why did GIO not flag these 10 users/email addresses last year ?
I do not know. The accounts were already disabled by Yahoo in
2019.
