I recently followed Falko's great guide for setting up an Ubuntu 9.04 + ISPconfig3 perfect server. I'm having problems retreiving a test user's email. I sent mail from an external account/domain. I can see the mail sitting in the user's new folder: /var/vmail/<my domain>/<username>/new/1244blahblahblah.<servername>.S=7384 Logging in to squirrelmail as: firstname.lastname@example.org gives the error: << ERROR: Connection dropped by IMAP server. Query: CAPABILITY >> Setting up Thunderbird to use IMAP seems to sit in a never ending loop of: connected to <server> checking... sending login information... Any help would be greatly appreciated. Thanks!
