[Solved] How to configure postfix to authenticate over starttls at relayhost?

Latest response

Hello all,

I could use some help with the configuration of postfix. I have to configure postifx to use SMTP Authentication when sending mails to a relayhost. The relayhost itself offers the following parameters:

telnet relayhost 25
EHLO localhost
250-relayhost
250-AUTH PLAIN LOGIN
250-AUTH=LOGIN PLAIN
250 STARTTLS

I would like to use STARTTLS to open a secure and encrypted channel and then transmit username and password for authentication.

Does anyone know a good tutorial or could explain how to do that?

Thanks in advance,
Joerg K.
