_________________________________

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?" 

Set permissions on the mail folder to 2775 because dovecot runs as its own user
and group and you need the mail file in that folder to accept writes from mail
and from dovecot groups.
Also in the config file dovecot.conf you need to specify if the files are
maildir or mbox. They are probably mbox but try both for the error messages.

Hello Shawn,

A very quick guess here...
Could it be that the dot in "/var/mail/mydomain.com/myuser" is  
interpreted as a hierachy separator?

HTH,
Axel

Ummm... upgrade??

Seriously... 1.0alpha?? When the current stable version is 1.2?

Like Charles said, v1.0 alphas are way too old. You really should be
using at least v1.0.0 or you're going to run into other bugs.

See the mail=/var/mail/mydomain.com/myuser output there.

default_mail_env is completely overridden by the mail= returned from
user_query. Add maildir: prefix to the mail field returned by
user_query.
