(RADIATOR) slightly OT: SMTP relay module

[Mariano Absatz]

For a differente (and IMHO more elegant) solution, you might like to check 
WHOSON:
http://whoson.sourceforge.net/
http://sourceforge.net/projects/whoson/

It's done by Eugene Crosser and consists of a very simple protocol that 
allows you to have an on-line list of "logged in IP addresses" to which you 
can "log in", "log out", "tiemout" and "query".

It's used with ZMailer (http://zmailer.org) to provide POP-before-SMTP 
authentication (by patching your POP/IMAP server to send a login). But it is 
designed with radius in mind so you can "log in" and "log out" from a radius 
server.

The API includes a Perl module, so you could call it directly from a hook in 
Radiator.

Regretfully, I still didn't convince any customer to use it this way, only as 
POP-before-SMTP, so we didn't still make such hooks.

In 
http://sourceforge.net/project/showfiles.php?group_id=16839&release_id=24410 
you will see a bunch of 3rd party patches, including one for sendmail (we 
designed the Courier-IMAP and the SolidPOP3d ones).
