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? ***solved
