I'm having a problem that I want to use Thunderbird in combination with the Enigmail addodn to send and recieve emails that are enrypted by PGP. I can already view emails that are sent to me as HTML, however, when trying to write an email, the formatting is lost.
I stumbled upon HTML or rich e-mails do not work with Enigmal in Thunderbird, but "Always use PGP/MIME" is already checked in my account settings and I'm sending both HTML and plain text as an email. I just want to use HTML in my signature. This is needed. How can I achieve that?
In AppleMail it works without any problems. However, I want to use either Postbox or Thunderbird.
UPDATE
I still can't fix this problem. I even used Postbox, which is based on Thunderbird, and I'm having the same problem there. Any ideas?
