Is it possible to send mails from Jira, with HTML content and attached plaintext, that the mail client can use, if he can't render HTML?
Background:
One of our customers normally views his mails in an e-mail client, that supports HTML and he likes having the additional benefit of seeing everything nicely formatted, but he also uses a device that is not able to render HTML. He told us, that they also use Jira and somehow configured it to send HTML & Plaintext in one E-Mail. This allows the mail-client to render the HTML if possible and fall-back to plaintext if not.
