You might want this option for postfix, have it bcc a new e-mail box on your groupwise server and setup rules that will 
delete all e-mails except those destined for your teacher or coming from that suspected student.

The postfix always_bcc parameter is what you're looking for: 
/usr/share/doc/packages/postfix/samples/sample-misc.cf: 

# The always_bcc parameter specifies an optional address that 
# receives a copy of each message that enters the Postfix system, 
# not including bounces that are generated locally. 
# 
always_bcc =

I run Postfix.  I looked at ProcMail but I can't seem to find any info when running PostFix as MTA or Relay...  I don't 
perform any local delivery at all.  Mail gets forward to GroupWise server.

Look at sendmail milter.  Create a milter rule the routes messages based on
keywords.

The legal question is not a problem.  But after thinking about this and
reading the various responses I have to agree that snort is not the right
tool.

I will look at doing this at the MTA level or Mail Server level.

thanks for all responses!

Snort is really not the appropriate tool for the job of email monitoring.
Before you even head down this road you need to get really good legal
opinion from school district legal dept. on privacy rights and various
federal and depending on your state laws that might apply.

I saw the following question in the archives and was wondering if this is

EMAIL FROM James...
"Wouldn't it be nice to be able to capture an _entire SMTP session_ based
on
a key word embedded somewhere in the SMTP message?  This could easily be
used to look for messages with a specific email address on them, with a
specific key word inside them, etc.

Anyone want to write an SMTP protocol handler?"

I'm interested in capturing email from a specific email.

thanks for any help.
