I use mail.app to access my school's IMAP account as well as my gmail account. My problem is that the program never seems to check for new mail until I open it, even if I already have mail running (triangle shows in the dock). I have the preference pane set to check for new mail every minute and I have downloaded IMAP-Idle, but neither seem to work. Anytime I open mail.app, I suddenly get a flurry of new mail notices from MailNotifier and MailUnreadMenu. Any suggestions?
