Postfix authenticate on forward to smtp server

LWillmann · 12-13-2007, 08:23 AM

I have to have my postfix server forward all mail to my ISP's smtp server. They have instituted smtp authentication. How do I configure Postfix to authenticate with my ISP's smtp server so that I can get my mail sent properly? As of right now, all mail is being rejected.

Read this. You'd need a postfix compiled with Cyrus SASL.

Code:

relayhost = isp.mail.server
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/isppasswd
smtp_sasl_security_options =

then you will need to create the /etc/postfix/isppasswd file with the content:

Code:

isp.mail.server    username:password

and hash it afterwards by:

Code:

postmap /etc/postfix/isppasswd
