Reading from /var/log/security is not especially user-friendly, and will be

Solution 3 avoids the complication of choosing, with virtually no disadvantage.

If this works, I'd say that it is the best solution, since it is very compact
(64k), and virtually every system will have the DNS it requires installed.
(Unless of course they don't have Internet or network access. In which case
msec would not be particularly important.)
Note that it is only at version 0.2 (or 0.3 upstream), so we should test it
carefully.
><i> 4. Try to fix nail, which is required by msec and so in every default
</I>><i> installation,
</I>><i> so that it is able to deliver mail by itself, without sendmail.
</I>
Solution #3 seems much better in every respect.

</I>
Solution 3, with changes/verifications noted below.
Since it is much simpler for the end-user to always have the capability to send
security alerts if an email address is entered, without installing anything extra.
There are 2 options at the bottom of the first security page of msec, which
should already realise Luc's proposals. They may have to be fixed.
a) An option to send a security alert by email, where one enters the email
address. By default it is checked.
However, if no valid format email address is entered, an email should _not_ be
sent.
As well, we should display something similar to
"(Enter {userid}@localhost for a local user.)",
to help ensure that the user enters a valid local address.
(Note that there are multi-line descriptions for all the other options above on
the same page, so this would fit nicely.)
b) An option to display security alerts on the desktop. Again, checked by
default. They should probably remain visible until the user dismisses them.
(They currently display for a few seconds, then disappear.)
My 2 cents :)
