Following the instructions on Mozilla’s website, I change the following setting in user.js:
user_pref("mail.check_all_imap_folders_for_new", true);
The idea is that enabling this option makes Mozilla check all folders for new email – important now that I’m doing more server-side filtering.
Once enabled I had a number of problems:
* After a random period of time, I wouldn’t see the contents of emails. Doing a mailbox rebuild fixed that. But it repeated, frequently.
* It would stop sending emails. I would get error messages when I tried to send.
* The addressbook would no longer work
* Various preference windows would be empty.
Very annoying.
I’ve now disabled that setting and normal functionality has resumed, and I’ve enabled it server-side, so I’m happy. However I’d now like to have the same server-side options configured at work – they’re using Dovecot, not Courier IMAP like I am. Can I find a similar option for Dovecot? Hell no.
Sigh.
