I've been attempting to remove the default email footer with limited success.
Rather than make modifications to the code directly, I found a quick tutorial from Ludwik Trammer:
http://stackoverflow.com/questions/26240062/how-to-remove-email-footer-in-odoo
After making his suggested modifications (and referencing https://github.com/Hansys/footer_remover ) I was able to successfully install a custom module that modified the footer text. However, it changed from this:
Sent by <<company name>> using Odoo about Lead/Opportunity <<lead name>>
to this:
about Lead/Opportunity <<lead name>>
Does anyone know how to modify the custom module code to remove the remainder of the footer text?
