Mark Sapiro reports:

A URL with a very long text listname such as
http://www.example.com/mailman/listinfo/This_is_a_long_string_with_some_phishing_text
will echo the text in the "No such list" error response. This can be used to make a potential victim think the phishing text comes from a trusted site.

This issue was discovered by Hammad Qureshi.
