Mailman ignores all headers that it is not specifically interested in.

You could use header_filter_rules to hold or reject incoming mail with
an Importance: header in an attempt to train users not to post with that
header.

The cleanest way to actually remove it would be with a custom handler
included in the pipeline for the specific list. See
<http://wiki.list.org/x/l4A9> for info on custom handlers.
