Enable SSP (port 993) and disable 143
I have used Ubuntu as mail server for a long time. And I have often installed it with help from howtoforge, thank you.
My question are:
in earlier "Perfect server" the IMAP (courier) did use (only) SSL and port 993. The last one, 10.04, did not. How can I enable SSL and disable uncrypted traffic on port 143?
