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.
First, can you accomplish what you want with a custom
list:member:regular:header template? See
https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/templates.html#templated-texts
If not and you need a custom handler, you have a couple of choices.
You can patch the default_posting_pipeline at
mailman/pipelines/builtin.py to add your handler to the
_default_handlers after installing it in mailman/handlers/. This will
require you to reapply the patch after any upgrade.
You can create a plugin which defines a new pipeline which includes your
new handler and set the posting_pipeline attribute of your list(s) to
the name of your new pipeline. See
https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/plugins/docs/intro.html
for some documentation and
https://gitlab.com/mailman/example-mailman-plugin/-/tree/master for an
example.
