If this mail client behaves anything like Apple mail clients, these
connection storms can come about when doing global searches. The mail
clients will march through each mailbox (opening a connection for each
mailbox) looking for a pattern.
If you can narrow this scenario for one specific user (e.g. $user), you
can deep dive what's going on by enabling IMAP session logs for this user
protocol imap {
...
rawlog_dir = /log/dir/%u
}
then
(Make sure this user has write permissions into this directory)
mkdir /log/dir/$user
After you're done, you can disable logging,
rm -rf /log/dir/$user
