Help getting Email2Trac to send HTML emails.

[kofal002@…]

I have performed a slight modification to Trac's source to send HTML notification emails. Really, I just added this line:

headers['Content-Type'] = 'text/html; charset=utf-8'

to NotifyEmail's send() function in trac\notification.py and it works fine. Whenever I respond to a ticket via Trac's webUI, Trac's notification email is sent using my custom templates\ticket_notify_email.txt, and the content-type is correctly flagged as HTML.

It would appear that Email2Trac uses the same code paths to send email:

def notify(self, tkt, new=True, modtime=0):
...
    tn = TicketNotifyEmail(self.env)
...
    tn.notify(tkt, new, modtime)

However, despite my best efforts to figure out why, Email2Trac-triggered emails are sent text/plain content-type. This is bad, since it's using the same custom (HTML) email template, but sending as raw text, and the HTML will not render. I've been digging through the code in both Email2Trac and in Trac's source, and I cannot find why this is the case.

This may not be in Email2Trac's main feature set, but I was hoping you could lend some insight on how to do this.

Looking at the raw email headers of the emails that do get sent as HTML (the ones sent via Trac's web UI), it looks like the content-type is getting set twice:

Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64
X-Trac-Version: 0.12.2
...
Content-Type: text/html; charset=utf-8

However, I can't find the code that sets the original "text/plain" header.

Crud! I was using two different python installations and forgot to modify them both!

Email2Trac wasn't to blame at all; my fault entirely :)
