How to get Thunderbird to work through HTTP proxy server

http-proxyPROXYthunderbird

I would like to access my personal IMAP server through my corporate firewall. This is allowed provided I use the corporate proxy server, which is an HTTP proxy server. I cannot figure out how to configure Thunderbird to honor this proxy server, though. It honors it for HTTP traffic, but not for IMAP and SMTP.

Thunderbird: 15.0
OS: OSX 10.8.1

AFAIK, there is no SOCKS proxy available, just an HTTP proxy. Also, the HTTP proxy allows other protocols to go through it (c.f. Can I tunnel other protocol through an HTTP proxy?). Using an add-on for a solution would be fine. Thanks!

My (oldish) Thunderbird has a checkbox in the "Connection Settings" to make Thunderbird use the http proxy setting for all protocols. Did you try that?

Otherwise maybe this helps?

In firefox type this in your address bar:

about:config
Click that you promise to be careful.
In the filter textbox, type: proxy
Find the preference name called network.proxy.socks_remote_dns. Double click it to set it to true.

Firefox will now proxy DNS requests instead of trying to resolve them locally.

HTTP Proxy – Can Other Protocols Be Tunneled Through HTTP Proxy

Besides the usual GET/POST/HEAD/PUT, many HTTP proxy servers understand an additional CONNECT request, which establishes a raw TCP connection to the remote host. This is required to properly support HTTPS, but can often be used for other protocols.

 $ nc proxy.example.com 8080
-> CONNECT mail.example.com:587 HTTP/1.0
->
<- HTTP/1.0 200 Connection Established
<- Proxy-agent: Apache/2.2.19 (Debian)
<-
<- 220 mail.example.com ESMTP Badger badger badger badger badger postfix postfix!
-> ehlo grawity-pc
<- 250-mail.example.com
<- 250-PIPELINING
<- 250-SIZE 10240000
<- 250-STARTTLS
<- 250-ENHANCEDSTATUSCODES
<- 250-8BITMIME
<- 250 DSN
-> quit
<- 221 2.0.0 Bye
