+MUA specific hints
+
+Some of patches I receive or pick up from the list share common
+patterns of breakage.  Please make sure your MUA is set up
+properly not to corrupt whitespaces.  Here are two common ones
+I have seen:
+
+* Empty context lines that do not have _any_ whitespace.
+
+* Non empty context lines that have one extra whitespace at the
+  beginning.
+
+
+Pine
+----
+
+(Johannes Schindelin)
+
+I don't know how many people still use pine, but for those poor
+souls it may be good to mention that the quell-flowed-text is
+needed for recent versions.
+
+... the "no-strip-whitespace-before-send" option, too. AFAIK it
+was introduced in 4.60.
+
+(Linus Torvalds)
+
+And 4.58 needs at least this.

+Thunderbird
+-----------
+
+(A Large Angry SCM)
+
+Here are some hints on how to successfully submit patches inline using
+Thunderbird.
+
+This recipe appears to work with the current [*1*] Thunderbird from Suse.
+
+The following Thunderbird extensions are needed:
+       AboutConfig 0.5
+               http://aboutconfig.mozdev.org/
+       External Editor 0.5.4
+               http://extensionroom.mozdev.org/more-info/exteditor
+
+1) Prepare the patch as a text file using your method of choice.
+
+2) Before opening a compose window, use Edit->Account Settings to
+uncheck the "Compose messages in HTML format" setting in the
+"Composition & Addressing" panel of the account to be used to send the
+patch. [*2*]
+
+3) In the main Thunderbird window, _before_ you open the compose window
+for the patch, use Tools->about:config to set the following to the
+indicated values:
+       mailnews.send_plaintext_flowed  => false
+       mailnews.wraplength             => 999
+
+4) Open a compose window and click the external editor icon.
+
+5) In the external editor window, read in the patch file and exit the
+editor normally.
+
+6) Back in the compose window: Add whatever other text you wish to the
+message, complete the addressing and subject fields, and press send.
+
+7) Optionally, undo the about:config/account settings changes made in
+steps 2 & 3.
+
+
+[Footnotes]
+*1* Version 1.0 (20041207) from the MozillaThunderbird-1.0-5 rpm of Suse
+9.3 professional updates.
+
+*2* It may be possible to do this with about:config and the following
+settings but I haven't tried, yet.
+       mail.html_compose                       => false
+       mail.identity.default.compose_html      => false
+       mail.identity.id?.compose_html          => false
+
