Catch all for dovecot authentication?

[Tobi]

Marc,

as stated by Aki

works fine and does what I want: accept any SMTP AUTH :-)
In my setup postfix has a catch-all anyway, so I can return
home=/dev/null in userdb

Saw the first tries on my server already. Just took 5min after enabling
SMTP AUTH :-)

@Aki: thanks a lot



Have a good one
