Easy, use:
  UNSUB=`grep -i "From: " - |head -1 |tr "<>" "  " `

The command tr is translate, and we're using it here to convert any < or > 
into a blank.  The rest of the script then handles it from there, looking 
for an isolated string that has a @ inside it.

BTW: A friend of mine came up with a more elegant solution for doing the 
unsubscribes...

 - In the aliases file, add an entry for the unsubscribe email:
     volleyball-unsub:  "|/home/mailman/ext/v-unsub"

 - Create the directory /home/mailman/ext
     mkdir /home/mailman/ext
     chown mail /home/mailman/ext
     chmod 0700 /home/mailman/ext

 - In /home/mailman/ext create the script "v-unsub":

#!/home/mailman/ext/bash_mailman
# This script runs as user mailman, but is only executable by user mail
# script to unsubscribe user from volleyball list
#   Mail to volleyball-unsub at haht.com
#   Subject: unsubscribe username at domain.com
UNSUB=`grep -i "Subject: " - |head -1`
for i in $UNSUB
  do
   /home/mailman/bin/remove_members volleyball $i
done
# End of script


 - Make the script executable:
     chmod a+x /home/mailman/ext/v-unsub

 - In the /etc/smrsh directory:
     ln -s /home/mailman/ext/v-unsub v-unsub

 - Copy and modify bash so that it runs as user mailman:
     cp /bin/bash /home/mailman/ext/bash_mailman
     chown mailman.mailman /home/mailman/ext/bash_mailman
     chmod 0555 /home/mailman/ext/bash_mailman
     chmod u+s,g+s /home/mailman/ext/bash_mailman

===

The directory /home/mailman/ext has rights such that only the mail user can 
access the files within.  The copied version of "bash" now called 
"bash_mailman" has it's ownership changed to mailman and then has it's UID 
and GID bits set.  Any script that runs using it as a shell will now run as 
the user mailman with group mailman.

Wahoo!
