ERROR: Connection dropped by IMAP server.

[sharp vonchaos]

Good afternoon.

First of all, I must praise you Falko for your brilliant How To's. I am quite new to Linux OS so please bare with me if I sound a little stupid at times. I have just followed your 'Perfect Server - Ubuntu 11.10' and got through it all virtually error free. The only problem I have is when I try to access Squirrel Mail, I get the error, as mention in the title of this thread, 'ERROR: Connection dropped by IMAP server.', and I am unclear as to what is at fault. I have looked through a few threads on this site, as well as a few others on the internet but I have failed to figure out what is wrong. I would be very grateful if anyone can give me a helping hand and point me in the right direction.
