I reported this for beta 2 but had no word on it, and it's still the same in RC1.
I've set up my IMAP account, and I have 3 new messages in by INBOX (double-checked in Thunderbird.) In OpenGoo, when I hit "check new messages" it says there are none.
If I change the username and/or password to be incorrect, it still says "email retrieval complete - 0 new emails" so it looks like it isn't even trying to contact the server.
Also it takes an age when editing/saving account details - any reason for this?
Great work on 1.2, it's coming along! I upgraded from 1.1 to 1.2-RC1 without any issues.
