I have just setup RoundCube Beta2 on Apache 2 with MySQL, and I can get to the login page, but it will not allow me to login. When I try to login, it just comes up with Login Failed. This is the error in /Logs - [07-Nov-2006 17:58:51 +0000] IMAP Error: Authentication for USERNAME failed (LOGIN): "a001 NO STARTTLS required" in on line 0 Now, I have it set to use IMAP on port 143 and TLS is configured on the server, Thunderbird uses it as does my current Webmail client - SquirrelMail (it works, but is ugly, which is why I wanted to try this one). What I get in the mailserver logs is - Nov 7 18:01:15 HOSTNAME imaplogin: Connection, ip=[::ffff:192.168.1.100] Nov 7 18:01:15 HOSTNAME imaplogin: DISCONNECTED, ip=[::ffff:192.168.1.100], time=0 I am running Debian Sarge with Postfix and Courier-IMAP. As I said, this works with no problems on Thunderbird and SquirrelMail. SquirrelMail is set to use the IMAP STARTTLS extension, not to append tls:// to the hostname. It looks to me that RoundCube is not sending/starting TLS, but I could be wrong. Can anyone shed any light on this? Thanks!
