162692 - IMAP folders disappear

Status: RESOLVED WORKSFORME

IMAP folders disappear occasionally. I use a large collection of folders and
sub-folders to categorise email. A typical folder name might be
mail/people/a/andrew high. I have hundreds of such folders.

Quite regularly, I will find that many of the folders have gone 'empty', in
other words, their subfolders have disappeared. /mail/people/a/ will show no
subfolders, or will show very few out of the total list.

Restarting Mozilla, which then fetches the list of folders again, brings them
all back OK.

I use mail in offline mode as well as online, but this does not seem to be a
factor as it happens irrespective of whether or not I have gone offline.

I use IMAP in 'mark as deleted' mode.

This problem appears to have disappeared in Thunderbird. Not sure exactly when.
