After I updated my server from Debian Sarge to Etch, my o so nice tweaked RoundCube stopped working (it used to work with no problem when the server was still in "Sarge" mode) The webmail page does showup nice, but it's not possible to login anymore. It's always giving me a login failed error (with email address or web ID) Looking at the RoundCube log files I see the following error: "IMAP Error: Could not connect to localhost at port 143: Connection refused in on line 0" Doing a "netstat -tap | grep imap" does indeed show me that I do not have imap2 running. When I did the update from Sarge to Etch at one stage it asked me something about configure the uw-imaps, and it did show me 3 options. IMAP2, IMAP3 and IMAPS. I only selected IMAPS, and "netstat -tap | grep imap" does show me that imaps is running. After the question about the uw-imaps it asked for a "Enforce port selection" for the uw-imaps. Here I selected yes. Anyway... Now.. How do I get IMAP2 up and running again? Can I just do a "apt-get install courier-imap courier-imap-ssl courier-pop courier-pop-ssl", and if so, will this change anything for the users who login with POP3? The server(s) are running ISPconfig. What is strange is that when I installed ISPconfig I did NOT install the Courier-IMAP / Courier-POP3 package, but RoundCube worked fine on my system!
