Why did my 'doveadm expunge' command not clear the Trash out of a mailbox?
The oldest messages was put into the Trash on the 26th June 2018 as shown in the file timestamp.

I was going to suggest that you dump the savedbefore dates on all your messages to see what Dovecot thinks your message's timestamps are. I tried it out myself and was surprised to find *all* messages in *any* mailbox I looked at gave the same timestamp -- probably that of the latest message.
For example,
# doveadm -f tab fetch -u {user} "uid date.saved" mailbox Trash
uid date.saved

Is this a bug, or am I not understanding what "savedbefore" means now? It certainly has changed behaviour since <2.2, since my script used to work before.
