Modify Mailing List: many functions not working

Hi!

I've been using qmailadmin for a while now, and these errors always
happened, so possibly it's something related to running gentoo-hardened. In
short, I cannot use many of the checkboxes to create/modify a mailing list.

1) Prefix outgoing subject headers with: <any string here>
results in "Internal Server Error" (no change for non idn domain)
apache error log has:

Unless there is a quick fix, I'd be at least very grateful if anyone could
point me to a workaround for points 2 and 3. I already found out how to
manually set a prefix from vpopmail, but I have no luck with the others, and
especially "reply to list" is quite important.

Bèrto
