Missing permissions

[Andrei Petru Mura]

Hi,

Dovecot version 2.2.36
In log files I get this error:
dovecot: imap(test): Namespace '': mkdir(/home/mail/domain/test/Maildir)
failed: Permission denied (euid=1005(vmail) egid=1005(vmail) missing +w
perm: /home/mail/domain, UNIX perms appear ok (ACL/MAC wrong?))

My authentication configuration is this:
passdb {
  driver = passwd-file
  args = username_format=%n /etc/dovecot/users
}

userdb {
  driver = static
  args = uid=vmail gid=vmail home=/home/mail/domain/%n username_format=%n
/etc/dovecot/users

}

/home/mail/domain/test directory is owned by vmail user.
How to fix this?
