I'd email, but this is of broader interest.

If you consult the UNIX Email Software Survey faq, you'll see that local
delivery agent adjunct programs such as "deliver", "procmail" and "mailagent"
provide programmatic mechanisms for doing things such as this.  This is
a simple permutation of the ubiquitous "vacation" program.  Deliver,
procmail or mailagent (you'll need Perl for mailagent) are probably the
least grief.  None of these packages require root access to install or
implement what you want.  Consult the FAQ for official sources of the
software and follow the instructions that come with the software.

I only have personal experience with deliver, which is particularly
easy to install and can do such things quite simply.  I'm doing far
more complex things than what you want.  If you take the deliver
route, I can send you some example filters which do things similar
to what you want.

Furthermore, if you're into hackery, you can usually do this with
your existing mail system (but you'll probably need root access):
	- sendmail via sendmail.cf hackery, or mail-to-pipe aliasing.
	- MMDF has filtering of various types
	- SVR4 mail
	- UUCP-style "rmail" - replace rmail with a shell script that
	  prescans the mail before handing it off to the real rmail.
Just about any mail software with mail-to-pipe capabilities can do this one
way or another.

Sure!  There are several "mail filtering" programs available; one of the
best of these is "procmail", which is availabel from many FTP sites.  Get
procmail and install it; you can then filter your mail to your heart's 
content.

The effectiveness of "talking to a sysadmin" varies greatly.  If the site
is commercial, you may very well succeed.  If, however, the site is aca-
demic, your chances are "not so good".

I'm the sysadmin for the UK College of Engineering (engr.uky.edu, NOT
ms.uky.edu (from which this posting originates)), and I routinely receive
messages such as "your user XXXX called me a YYYYY on the mailing list!
Terminate his email NOW!".  I usually get a chuckle from this.  I've never
rescinded a user's email privileges; with the exception of illegal activi-
ties (emailing pirate software after repeated warnings, for example), I 
doubt that I ever will.

One must accept the good with the bad.  If you enjoy full communications
privileges (and wish them extended to others), you WILL, eventually, be
offended.  It's part of the virtual territory.

Yes... you can use the filter program, if elm has been installed on your
system.  If you haven't run elm before, run it once so that it can create
the appropriate directories in your account.  Then, you have filter invoked
by the reception of new mail by putting "| /usr/local/bin/filter" (with the
quotes) in your .forward file (the directory may be different from system
to system; type "which filter" to get the appropriate directory).  Finally,
you set up a filter-rules file in your .elm directory, which might contain
the following:

if (from contains "unwanted-person-name") then save unwanted.message 
#alternatively, replace "save unwanted..." with "delete"
if (always) then leave

Be sure to check your filter-rules out for proper working order by
running "filter -n < sample.msg" on both messages which should be deleted and
messages which should be saved (including the header); filter will tell you what
it would do with the message if run with the current filter-rules.

Check the filter man page for more information.

I suggest using MH.  There are manuals in the library.  Basically, you can create a .forward file that looks like this:

"| /local/lib/mh/slocal -user schwager"

and then you can have a mail delivery file that looks like this:

from nastyperson qpipe ?: "/bin/cat > /dev/null 2>&1"
addr schwager qpipe ?: "/local/lib/mh/rcvstore +Sysadm"

Automagic!

Many more configuration options are available.
