I tried overriding the protection by adding port 143 to network.security.ports.banned.override, and then I got "This request was not recognized. Perform a trace." in the message area, possibly from my proxy, which would be even more bizarre. Reproducible: Always Steps to Reproduce: 1. Click on an IMAP account's inbox 2. Click on a message Actual Results: See above Expected Results: Display the message body :)
I'm guessing your imap server wants you to use SSL - just configure your imap server account settings in Mozilla to use SSL. I don't think this is a client bug - i think your server administrator just turned off access to IMAP on the default, non-SSL port. I could be wrong, but that's what it sounds like.
No, I really think it's a bug. I've got 2 IMAP accounts and the problem occurred on both. I switched back to an older nightly now, and they're both working properly again.
yes, sorry, that is Mozilla code giving you that error message, but it's not the IMAP code. Do you have other ports disallowed? There must be something about your configuration that's special since the vast majority of users don't need to do anything with network.security.ports.banned.override - The IMAP code allows IMAP to be run on any port. Do you have port 143 on your banned list? Perhaps the necko code that handles overriding banned ports is broken...
I've been having the same problems since the proxy-auto-config failover changes were committed but nobody else was able to reproduce. I see the problem on both Solaris and Linux with an proxy.pac file referenced by a file: url. If the default result is DIRECT then imap works, if it points to a PROXY then imap urls are sent to the http proxy which gets confused. This is a serious regression.

Ever confirmed: true
I've never changed anything to the banned ports except the override I mentioned earlier on, but I removed that one again. As far as I know, my port configuration is normal. But I _am_ using a proxy through PAC.
