Hi, Today I got an Email from my ISP indicating that by next Tuesday I need to tell my mail client to authenticate when connecting to my smtp server. This is aparently to help fight spam, which I understand. However, I'm currently sending mail to my local Linux box and having it relay it to my ISP's server. Is there a way to tell Postfix to authenticate with the remote server when it relayes, and if so, how? Thanks, Jayson.
