Enclosed are patches to snort 1.8.2 to allow adding a new alert plugin, 
alert_smtp.

This acts exactly like alert_smb and in fact was taken from  Andrew 
Baker's alert_smb. (Thanks Andrew)

there is no command line alert option, so this must be activated with 
snort.conf options:

output alert_smtp: /usr/local/share/snort/smtp-names-file

Where smtp-names-file lists newline delimited list of email addresses to 
send alerts to.

configure file allows --enable-smtp-alerts

There are no win32 compile options (someone else might want to apply 
these?)  

smtp headers are controled by the spo_alert_smtp.h file, samples as 
enclosed have these headers: (sets prty flag on *nix and *dos systems)

Additional headers could be added prior to compling such as X-Loop, reply 
addresses, etc.

(to and from different since my anti-spam system dumps most email with to 
and from the same)

#define SPO_ALERT_HEADERS "X-Priority: 1\n"     \
                          "Importance: high\n"  \
                          "To: Snort-User\n"         \
                          "From: Snort\n"

Anyway, 8 patches, patches to 
patch-01:--- Makefile.am.orig   Fri Nov  2 11:22:36 2001
patch-02:--- Makefile.in.orig   Fri Nov  2 12:04:14 2001
patch-03:--- configure.orig     Fri Nov  2 12:04:17 2001
patch-04:--- configure.in.orig  Fri Nov  2 11:17:26 2001
patch-05:--- plugbase.c.orig    Thu Nov  1 21:09:38 2001
patch-06:--- plugbase.h.orig    Thu Nov  1 21:09:38 2001
