I installed ispconfig on ubuntu(http://www.howtoforge.org/perfect-server-ubuntu8.04-lts
And I can't send mail to certain mail services like gmail(although it can get mails from gmail).
I understand that there is a PTR record problem and the only way that I can get mail out to gmail is to use a relay threw my ISP.
I followed these steps:
in the etc/postfix/main.cf file i put :
relayhost = out.myISP.net
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sender_dependent_authentication = yes
and I oviesly make a sasl_passwd file and hash it.
and still get an error what do I do wrong?
