New test
step 1.
initial state inbox and deleted
[@ testtest]# doveadm -o mail_location=mdbox:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index mailbox status -u testtest 'messages vsize' '*' Sent messages=17 vsize=7473 Drafts messages=6 vsize=67170 INBOX/test2 messages=198 vsize=12552420 Junk messages=2 vsize=1969 Deleted Messages messages=0 vsize=0 Trash messages=47 vsize=769284 INBOX messages=1117 vsize=207623033
[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index mailbox status -u testtest 'messages vsize' '*' Sent messages=0 vsize=0 Drafts messages=0 vsize=0 INBOX/test2 messages=0 vsize=0 Junk messages=0 vsize=0 Deleted Messages messages=0 vsize=0 Trash messages=0 vsize=0 INBOX messages=2 vsize=89284
step 2.
check if we have messages indeed stored
[@ testtest]# grep 45765765870 /home/popusers/testtest/mdbox/storage/* /home/popusers/testtest/mdbox/storage/m.893:Subject: New file uploaded 45765765870
step 3.
delete 5 messages including the one having subject '45765765870' from inbox/test2 mailbox with thunderbird shift+delete, restart thunderbird (otherwise nothing happens on server)
step 4.
verify if messages are indeed deleted, looks like ok, indeed 5 fewer messages.
[@ testtest]# doveadm -o mail_location=mdbox:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index mailbox status -u testtest 'messages vsize' '*' Sent messages=17 vsize=7473 Drafts messages=6 vsize=67170 INBOX/test2 messages=193 vsize=12296609 Junk messages=2 vsize=1969 Deleted Messages messages=0 vsize=0 Trash messages=47 vsize=769284 INBOX messages=1117 vsize=207623033
step 5.
verify refcount=0 messages in folders, not ok, INBOX/test2 should have 5
[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/popusers/testtest/mdbox:INDEX=/home/popindex/testtest/index mailbox status -u testtest 'messages vsize' '*' Sent messages=0 vsize=0 Drafts messages=0 vsize=0 INBOX/test2 messages=0 vsize=0 Junk messages=0 vsize=0 Deleted Messages messages=0 vsize=0 Deleted Messages/test messages=0 vsize=0 Trash messages=0 vsize=0 INBOX messages=3 vsize=90243
