I updated imapd and imapd-ssl from
4.3.0 (IIRC) to
4.3.1 today, and it
stopped working in a weird manner:
1. My client (thunderbird) behaved as if there were just no new mails in
any folders. (SSL handshake successful.)
2. TB has index files to cache the subject lines of known mails, so I
could klick on mails known to be present on the server. I was presended
an empty page.
3. I could not save any messages anymore.
I believe, the IMAP-server just did not reply with any data, and
therefore not produce an error either. I did not get any error messages
in logfiles or from TB. No hints, no nothing. It was just - well, blank.
I downgraded imapd and imapd-ssl to
4.1.1. and everything is fine again.
As I used the new config file and filled in my personal settings from
the old one, I don't think I had a problem with my configuration. I use
SSL and REQUIREPEER, so it is quite hard to analyze problems like this
in detail.
Is there any way I can make courier more talkative next time I have a
problem like this? (Which is actually quite often.)
