[MM3-users] adding personalized email header/content in mailman 3

adding personalized email header/content

Hello,

I'm upgrading from mailman 2.1 and need to have personalized email header and content. In 2.1 eventually (couldn't get custom handler work) I had to modify Decorate.py handler. Basically encrypting email and passing it as a parameter in google required One-click unsubscribe email header link (same in the message body).

I tried creating a custom Handler (custom_header.py) in 3.3.19, adding outgoing_pipeline = custom_header in config [mta] section but it doesn't seem to be activating.

Thanks
