When I try to load a message on an IMAP server, I get a dialog box stating
access to the port has been disabled for security reasons, followed by an IMAP
connection error dialog.
I tried overriding the protection by adding port 143 to, 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 - 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.
