Hi folks,

I have some clients who get their mail via UUCP over IP.

To save bandwith I made two wrappers that compress/decompress the mails.

rmailwrapper.sh is used as wrapper for rmail. It also works, if the incoming  
mail is not zipped.
uuxwrapper.sh is used as wrapper for uux. It gzips the files before calling  
the real uux.

Comments are welcome!


To install use

cd /usr/libexec/
mv rmail rmail.org
chmod a+x rmailwrapper.sh
ln -s rmailwrapper.sh rmail


cd /usr/bin/
mv uux uux.org
chmod a+x uuxwrapper.sh
ln -s uuxwrapper.sh uux
