[ale] Sendmail and dial in users

[Christopher Fowler]

I have a sendmail server adn I would like my users to be able to use it as a
SMTP server when they dial into mindspring.

I have only a few domains in /etc/mail/access

Is it possible to allow them to relay if the 'MAIL FROM:<USER at WHATEVER.COM>'
is listed in /etc/mail/access as:

USER at WHATEVER.COM			RELAY

I tried this but it seem to deny relay when I did the below:

telnet mailserver 25
helo whatever.com
mail from: <user at whatever.com>
rcpt to: <user at awayfromhere.com>
---- RELAY DENIED

Is it possible to do this with sendmail?
