Default Updating SMTP server to use SSL/TLS

Hi all,

I've been running ISPConfig 3 on Ubuntu 10.04 for almost 2 years without any problems. However, in all that time, I've only ever received email though it; I've never needed to send mail.

That changed today, and it took me a long time to figure out that somehow my SMTP server (I think I'm using courier) is set up without SSL/TLS on port 25, so my authentication details are sent plain text.

I'm not a server admin (hence why I use ISP Config in the first place), so if someone could give me pointers as to how I go about switching on encryption, that would be awesome. I've done some typical google/forum searches, but nothing comes up which seems to meet my needs.

Any help is appreciated!

Th smtp server that you use is postfix, courier is the imap and pop3 server. To enable smtps in postfix, edit the file /etc/postfix/master.cf and remove the # in front of the line that starts with smtps and the 3 next lines after that line. Then restart postfix.

Get ISPConfig support and the ISPConfig 3 manual from ispconfig.org.
