Comment(by tagnaq):

 Replying to [ticket:6314 tagnaq]:
 > Sukhbir is preparing a patch for Thunderbird that will allow us to send
 emails without Date header field.

 patch is available here:
 https://raw.github.com/ioerror/torbirdy/master/patches/date.patch

 If anyone want to help us to test it with many freemailers:
 1. apply the patch to thunderbirds source and recompile
 2. create a new preference and set it to false:
 {{{mailnews.local_date_header_generation = false}}}

 send your self an email and tell us whether the email in your Inbox
 contained a proper Date header.

 Here are a few popular freemailers that would be good to test with the
 patch applied:
 - yahoo
 - hotmail
 - hushmail
 - gmx
 - mail.ru
 - yandex
 - mail.com
