If you want all URLs starting with "http://external-server/mailman" to
be forwarded to corresponding URLs at "http://internal-server/mailman",
this is the correct syntax.  If in fact what you want is something
different, be specific.

Without seeing the rest of the URL space configuration it's hard to
guess what might be wrong.  What do you mean by "doesn't work"?  What
errors are produced in the browser?  What is in Apache's log?  Check
Apache's error log as well.

Given that

 > http://external-server/listinfo  >> http://internal-server/mailman/listinfo

"works" (I assume you mean that produces the listinfo page from the
Mailman installed on internal-server), I would guess that you have
some configuration on external-server that interferes with configuring
/mailman with ProxyPass.  Was Mailman ever installed on
external-server, so that there is an Alias or ScriptAlias for the path
/Mailman on that Apache?  Perhaps you have a Location or Directory
element blocking the ProxyPass.
