> This is my 6th day installing my first Postfix/Dovecot installation. The Postfix mailing list indicates I've got the MTA under control so now I'm seeking your help with the MDA. I get these errors with legitimate email addresses:

You should test:

    mysql -udovecot -pxxx -hlocalhost postfix

to simulate the dovecot attemts.

> I've noticed that every time I restart dovecot I get this error in the dovecot-deliver.log:
> Oct 24 11:31:11 lda: Error: userdb lookup: connect(/usr/local/var/run/dovecot/auth-userdb) failed: Permission denied (euid=512(vmail) egid=512(vmail) missing +r perm: /usr/local/var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755)

> Every time I go to chmod 666 on that file, restarting dovecot wipes those permissions. How fix?

This file is not a file, it is a socket and gets recreated every time
you restart dovecot. There is, if I remember well, some config option
"mode" near the name of the name of the socket.
