Enigmail replaces '>' and leading spaces, 'Flowed Text'

[barry]

Enigmail replaces ">" in quoted messages with "|" and spaces with "~"

This is not really a bug, but a workaround that Enigmail uses to handle the text=flowed formatting used by Mozilla, which can invalidate signatures.

You can avoid this replacement by setting the option mailnews.send_plaintext_flowed to false.

• Thunderbird: open the Config Editor (Tools > Preferences > Advanced)
• SeaMonkey: open the URL about:config

format=flowed (RFC2646) causes problems with OpenPGP signatures.
DON'T use it.

In Seamonkey, open a browser window to about:config,
in Thunderbird, use the "Config Editor" button located on the General tab under Options --> Advanced and
make sure that mailnews.send_plaintext_flowed is set to false.
