After downloading and upgrading to Mozilla 0.9.9 I was unable to connect to the IMAP mail server at work. The mail server returns the following when telnetting to port 143: Solstice (tm) Internet Mail Server (tm) 2.0p12 IMAP4 service Presumably this is a very old mail server as our corporate standard is supposed to be iPlanet Messaging 5.0 When trying to connect to the mail server, the status bar shows activity but nothing happens for quite some time until it times out and says the server has refused the connection. After trying numerous different ways of installing/uninstalling, etc I had to go back to 0.9.8 which performs slowly but satisfactorily.
Reporter: Do you use a proxy ? If yes: Have you a "no proxy" entry for your Imap server ? (BTW: we changed this betwenn 0.9.8 and 0.9.9) You can read this in the release notes (and you should read this before you file a bug)
Same observation here with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020529 we are also using SIMS as mailserver. Some more investigation: Running a network sniffer shows, that despite networking is set up correctly (dns works, servers are reachable via telnet (manually typing IMAP commands works fine)), Mozilla does not even initiate network traffic to the IMAP server. To verify that I was using the network sniffer correctly, I shut down mozilla, and started another mail client (netscape 4.79) to connect to the mail server - which worked without problems. Restarting mozilla with IMAP logging enabled (NSPR_LOG_MODULES=IMAP:5) just reveals one line: 8201[874b2d0]: <servername>:NA:CreateNewLineFromSocket: (null)
Christian Funke : Do you use a proxy/socks server ? (for http...)
Hello Matti: Yes - and I just verified, that in fact things work again if I put the domain the imap server is in into the "No Proxy for:" field. This is _very_ strage behavior, because there is no indication for the user that the proxy setting may interfere with IMAP functionality...
CC bbaetz for the last question bbaetz: Maybe we should add a pref "use Proxy for Mailnews" ? We got many bugs about this and also many people ask in the newsgroups about this..
Such kind of button would help very much. From the current point of view, it is not even clear which proxy is used, as you can specify different ones for different protocols, but not for mailnews.
AFAIK only Socks

If you don't have a SOCKS server, then don't tell mozilla that you do. I'm open to suggestions to make this more obvious, since lots of people just fill in everything with the same server name. Sugestions?
How about adding a checkbox "Use SOCKS proxy for Email"?
Not really... Are you actually in the position of having to use a socks proxy for external sites, but internal web sites do work AND your domain isn't in the no proxy for field AND it doesn't work for external sites? That situation is really unlikely. I think we just want to indicate that 'filling in all the boxes' probably isn't want you want. A separate group box, maybe? mpt, thoughts?
We have a bug about adding a "proxy for all" field. We could do this and put the socks pref in an own group.
-> invalid (the problem itself is invalid)
verified invalid. there are open bugs about moving/extending the 'no proxy for' UI into mail accounts.
