_________________________________

I verified that "default_mail_env" on my dovecot configuration file are "maildir:" correctly prefixed:

"default_mail_env = maildir:/var/mail/%d/%n"

and ... permissions of /var/mail/mydomain and /var/mail/mydomain/myuser are 2755 and owner is root:mail.
I'm sure that isn't an authentication problem.
I've tried some days to understand and to find over internet and here in the dovecot mailing list but I've not find a solution yet.
I think it's a dovecot internal bug.
Someone know what I'm talking about?
