Hi there I've tried twice now to follow this guide: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-debian-lenny Firstly, thanks to the author Falko for his efforts. Thinking I had made a mistake the first time, I blew everything away and followed the guide a second time. Both times however when attempting to use IMAP with SSL, it fails to authenticate and the only error in the log is: imapd-ssl: couriertls: /etc/ssl/certs/edc85c27.0: No such file or directory Of course edc85c27.0 doesn't exist in /etc/ssl/certs. Can anyone shed some light on how to fix such an error? Cheers!
