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!
