Hi all,

The prior message from the list (below) was received at 17:23 local time;
just 39 minutes earlier.  Emails from other senders arrived at 17:14,
17:23, 17:55, 17:55, (bounces here? Notified at 18:02), 18:03, 18:12, ...

I got kicked for bounces, yet the notification made it through...

Maybe this was a network error; temporary DNS failure near claws-mail.org?

How often are the messages retried? 

The problem had to be limited to the time span between 17:23 and 18:02 my
local time, from claws-mail.org [217.70.191.162]'s perspective.

Just checked my MTA (luxsci.com)... Turns out they keep up to 100 emails
daily in a BACKUP folder; everything in there matches the Inbox. No sign
of problems since other messages came in right around the "bounce" time. 

Is it possible to get a full copy of one of these bounce messages?  I
suspect whatever triggered the bounces was not from luxsci.com...

Suggestion: bounce message(s) should be copied into the notification.

Answers might help improve the bounce handling process...

Cheers,
Pierre
