Hi Aki,

Thanks for your answer !

I've just gived a try and it works partially :

- the "userdb_mail=maildir:~/Maildir" is well taken into account for
my user in "/etc/dovecot/overrides" (testm2m_mydomain.tld)

BUT

- all other accounts (located in "/etc/passwd" and not in
"/etc/dovecot/overrides") could not connect anymore to the Dovecot
server (POP/IMAP...). I got this kind of message in mail mail.log :

8<------------------------------
Feb 13 21:58:14 mail dovecot: imap: Error: Authenticated user not found from
userdb, auth lookup id=2769158145 (client-pid=27095 client-id=1)
Feb 13 21:58:14 mail dovecot: imap-login: Internal login failure (pid=27095
id=1) (internal failure, 1 successful auths): user=<xavier_mydomain.tld>,
method=PLAIN, rip=x.x.x.x, lip=y.y.y.y, mpid=27096, secured,
session=<N2VZZ4v0oNABJ3LB>
8<------------------------------

Any idea ?

Thanks for your help !

Try adding both

skip=notfound

and

result_failure = continue-ok

to ignore the not found error, to the override db.
