Hello I have accounts with Maildir (mail_location is empty/default)

successful delivery but no new file anywhere in the Maildir:

/home/me/Maildir/new is empty and also try "find /home/me/Maildir
-type
f | wc -l" but no different before/after
Very interesting I can see trace of message in dovecot cache! "grep -r
'domain.from.message.id' /home/" (search all accounts) says:
grep: /home/me/Maildir/dovecot.index.cache: binary file matches
So dovecot put traces of message into Maildir but no message file
after
successful "Saved" in logs.
What can I do?
Can you post doveconf -n? Also you can enable mail_debug=yes logs to
see more details.
Thank you for reply. I had monitored and now some messages are stored
correct in the problem accounts, but not sure if delivery count matche
file count. Could a connected/idle IMAP client pull messages from server
(delete server copy) without notification in log file and leaving
message traces in the dovecot cache file? (is that possible
explanation?) Postconf is mostly defaults from package install. Ill turn
debug yes if i can verify the problem still happening.
