Hi, I have TLS turned on on my server but since that server also accepts incoming mail from the internet, I can¹t require it¹s use and so it is certainly possible that some of our users using AUTH-SMTP are still connecting unencrypted. Currently the only authentication mechanism we are using is PLAIN and so I want to use CRAM or DIGEST MD5. All the helps I can find on the web give instructions on building from source but I¹m running a RedHat Enterprise server and all the libraries are already installed. The problem is that I can¹t find any instructions on how to configure to use mechanisms beyond PLAIN and if I specify noplaintext in main.cf, Postfix just hangs.
Is anybody using any of the secure authentication mechanisms and would you be willing to share your configuration with me? Thanks, Rob Rob Tanner UNIX Services Manager Linfield College, McMinnville Oregon
