Hi,
I try to make a CGI to enable a user forwarding his mail to another place.
As far as I understand I have to change to the user-ID and group for modify
the .forward-file in his directory. Now, on the apache (1.2.4) there is a
small note on how to use the suEXEC ("...accomplished by using the
~character perfixing the user ID...). I have no idea what this means. Has
anybody an example of how to use this (or even better a complet perl-CGI
for mail forwarding).

Thanks
Rolf

A CGI script that modifies files in users' home directories is a
dangerous beast, even in the hands of a veteran hack who would never
need to ask how.  A Perl CGI script is doubly so (although taint
checking helps a lot) which is one good reason it will not work
at all under 'default' CGI conditions.

If you want a system that permits users to control incoming mail
processing (including forwarding) via the Web, take a look at
<URL:http://www.webthing.com/>.  WebThing can (optionally) use
the .forward mechanism, but will never touch the file.

Now, if you still want to edit users' .forward files, you'll either
have to give every user their own copy of the CGI script, or run
something SUID root (badbadbad...)
