used by the SSL/TLS connection. Default is `true`. Ignored when
imap.tunnel is set.
+imap.preformattedHTML::
+ A boolean to enable/disable the use of html encoding when sending
+ a patch. An html encoded patch will be bracketed with <pre>
+ and have a content type of text/html. Ironically, enabling this
+ option causes Thunderbird to send the patch as a plain/text,
+ format=fixed email. Default is `false`.

+CAUTION
+-------
+It is still your responsibility to make sure that the email message
+sent by your email program meets the standards of your project.
+Many projects do not like patches to be attached. Some mail
+agents will transform patches (e.g. wrap lines, send them as
+format=flowed) in ways that make them fail. You will get angry
+flames ridiculing you if you don't check this.

+Thunderbird in particular is known to be problematic. Thunderbird
