Unhappy Question regarding sendmail AUTH / Relaying denied


I´m using ISPConfig 2.2.10 with Centos 4.4 and sendmail 8.13.1. I´ve been trying to configure SMTP auth so any user that would like to use the server for sending mails anywhere should authenticate first with its POP3 login.

I´ve followed the tutorials, and the suggestions from the forum, but I´m stuck where the user can only send mail to local accounts and when trying to send to another domain (i.e. gmail, hotmail) it gets the following error:

reject=550 5.7.1 <user@gmail.com>... Relaying denied, IP name lookup failed []

Of course if I add RELAY

to /etc/mail/access, i get no message and then the user can send. But my question is, isn't the SMTP auth option precisely a way to avoid entering each IP address to the /etc/mail/access file so any user can send mails as long as the user authenticates? Or is it that even if I define SMTP auth I should include in /etc/mail/access all the IPs from the users that are going to use the server?

By the way, when I do:

testsaslauthd -u web1_user -p password

I get "OK Success" so it seems the SASL config is working. And also, if I do

telnet localhost 25
EHLO localhost

I can see 250 AUTH LOGIN PLAIN, so it seems the config is also in place.

Thank you and regards,
