Hi Jim...

The version of Zmailer that is in the CSuite distribution does not
include much in the way of anti-spam tools... the newer versions do... I'm
not aware of any security issues associated with the included version.

Our inclusion of zmailer is linked to some of the mailing list
administration tools (an interface of sorts for majordomo). These go
quite deep into CSuite, and we're in the process of re-doing this area.

As example of the complex relationships...

The IP (information provider) creation routines... are designed to create
two mailing lists (one private - for comments on the web-page... etc; and
one public - for communications with all interested parties.)

Mailing list creation (and maintenance) normally requires root access and
involves manipulation of the system mail aliases.

The version of zmailer that is part of the distribution includes
modifications that provide for separate mailing list aliases...

-----

As I mentioned, we're in the early stages of reviewing these systems. 

On _our_ main system we've upgraded to a newer version of zmailer that
provides the anti-spam tools we're looking for. Unfortunately that
also means we've gone back to manually dealing with mailing lists. This
may not be a good option for some sites...

-----

A new version of majordomo is in the works... (no date that I know of) the
new version deals differently with aliases and the implications of this
have not been sorted out.

-----

A central goal of CSuite is to allow volunteers ( who do not have
technical/sys admin priveleges ) to undertake activities like activating
information providers... if you have good technical resources (can manage
the mailing lists manually)... and are committed to sendmail we should be
able to provide some assistance to get the mailing list management tools
adapted... we definitely want to move on that ourselves although for the
moment we're not likely to move to sendmail....

It looked like such an easy queston eh... ;-)
