We come from a Google Groups background and many users still rely on mailing list mode. Some mailing list emails, from the same topic, are not sent. Here is an example for a single user, from the email sent page. Why were #371 and #372 not sent?
This is just one example sequence, there are many more skipped emails
The user has not muted the topic
The user was not the author of the skipped posts
There is nothing for this user in the email skipped or bounced pages. The user never visits the forum and the posts were not skipped for “user has been seen recently”.
#371 and #372 have not been deleted- nothing unusual about them
A small clue: The skipped emails vary by user. The user above did not receive #371 or #372. Another user received those, but did not receive #369 or #375. A third user has yet a different pattern.
Does the mailing list skip if a user has been seen recently? Or is there a per-user limit?
