Hello List,

First of all, this is my first post so please bear with me if I miss something.

I'm using Postfix with Dovecot 2.0.19 as the LDA. The home directory is of the form /var/mail/virtual/<domain>/<username>. The mail directory is under the home directory and named mail. mail_location is left empty, and userdb is specified using SQL:

user_query = SELECT uid AS uid,
gid AS gid,
homedir AS home,
maildir AS mail
FROM users WHERE email = '%u'

Everything had been fine, until I added a new user. In the log, Dovecot complains that it doesn't have permission to create the mail directory (email address replaced):

Jan 2 05:46:19 mail1 dovecot: lda(test@test.com): Error: user test@test.com: Initialization failed: Initializing mail storage from mail_location setting failed: mkdir(mail) in directory /var/spool/postfix failed: Permission denied (euid=5000(virtual) egid=5000(virtual) missing +w perm: /var/spool/postfix, dir owned by 0:0 mode=0755)

Sometimes it complains about /run/dovecot instead of /var/spool/postfix, but I think that doesn't really matter. I think not specifying mail_location confused Dovecot, as explained in MailLocation. When I put in the right value for mail_location the error went away.

What I don't understand is, it is said in the same document that the userdb field mail will override mail_location anyway. I would think that I can skip mail_location if I specify userdb mail for all users. Is the document wrong?

Thanks, Phu
