Ignoring Jinja/Django syntax

[msert29]

I wanted to use premailer to compile my email templates however it seems that there are no options to ignore Jinja or Django syntax.

As an example

{% if user.age > 18 %}
....
Gets compiled into this

{% if user.age > 1 %}

Wondering if there is scope to add an option to completely ignore django and jinja syntax?

I have used the preserve_handlebar_syntax=True as well but no luck either.
