I have confirmed this with multiple attempts.

I start a new message in Thunderbird.  Then I wait around for that 
message to be auto-saved to Drafts.  When that happens, I see an "add" 
request in the solr log.

Then I send the message.  At that point, I see another add in Solr's 
log.  Based on the message number in the add request, I know that this 
time the add happens in the Sent folder.  But despite the fact that 
Thunderbird deletes the message from Drafts, Solr never sees a delete 
request.  My dovecot version has been updated since the last time I 
indicated what version it is.  Now it is "2:2.3.17-3+ubuntu20.04" from 
the dovecot repo, not the ubuntu repo.  The same thing happened with 2.3.16.

As I mentioned in the first message on this thread, when shift-delete is 
used in Thunderbird to delete messages, that also never sends a delete 
to Solr.

Something somewhere is misbehaving.  Is it Thunderbird accessing IMAP 
incorrectly, or is it Dovecot?

I will do a packet capture to see if maybe dovecot is sending requests 
that are not logged by Solr.  That seems unlikely -- even bad requests 
should result in some kind of entry in the solr log.

Thanks,
