qmail 587 only authenticated

[split]

Hi,

I want to use the TCP:587 port to authenticated email users. How to open this port is easy; just create a new file in xinetd.d with "service submission".

The problem is that I want that this port only accepts authenticated email. Now I have:

/var/qmail/bin/relaylock /var/qmail/bin/qmail-smtpd /var/qmail/bin/smtp_auth /var/qmail/bin/true /var/qmail/bin/cmd5checkpw /var/qmail/bin/true

Any idea?
Thanks!

Hi,

using this:

seems to work, but only "seems" :(
As I've read in other posts, SMTPAUTHUSER environment variable is not defined by Plesk's qmail so the plugin can't see the authenticated user.
