I followed the perfect server guide for ubuntu 7.10 all the way through to the end of ispconfig. I've been trying to change the send port for e-mail to port 465. I've searched the forums, google, etc..., but nothing i've found seems to work. I tried changing the port in /etc/services, I've tried changing /etc/postfix/master.cf I've tried commenting out these lines: "#smtps inet n - - - - smtpd # -o smtpd_tls_wrappermode=yes # -o smtpd_sasl_auth_enable=yes" I've tried changing "smtp inet n - - - - smtpd" to "465 inet n - - - - smtpd" I've tried a lot of different things, but it always results in ispconfig not being able to find the smtp server. Can anyone help?
