How to install protector 1.00.11 for RedHat Linux or Sun Solaris

To compile and install protector-1.00.11 you will need to have the GNU make (gmake) and GNU C compiler (gcc) Compiler software installed on your machine. For RedHat linux, these are included on the standard installation CDs. For Solaris, you can download them free of charge from http://www.sunfreeware.com. You must then ensure that /usr/local/bin is included in your PATH setting before this procedure can be used.

To install the programs, scripts etc..

        gmake build
        gmake install

To install protector for use with the default mail server "sendmail", you must edit the /etc/sendmail.cf file to replace the references to program "procmail" with "protector", there are two ways of doing this, depending on how you sendmail.cf file was generated.

Sendmail configuration - alternative 1 - sendmail.mc

If you generate your sendmail.cf file using the sendmail.mc and "m4" method (you will know if you do), then change (or add) the following two lines to the file (check out alternative 2 if you use RedHat's linuxconf or other methods instead). ..

define(`LOCAL_MAILER_PATH', `/usr/bin/protector')
define(`PROCMAIL_MAILER_PATH', `/usr/bin/protector')

Note that the PROCMAIL_MAILER_PATH definition should appear before the "MAILER(procmail)" line in the file (if it exists). The LOCAL_MAILER_PATH definition should appear at the end of the file.

Then regenerate the sendmail.cf file as usual, using the command..

m4 sendmail.mc > sendmail.cf

Sendmail configuration - alternative 2 - sendmail.cf

If you do not use the "sendmail.mc" method of generating you sendmail configuration, then you should edit the /etc/sendmail.cf file directly. The following two changes need to be made..

First edit

Mlocal,         P=/usr/bin/procmail, F=lsDFMAw5:/|@qSPfhn9, S=10/30, R=20/40,
                T=DNS/RFC822/X-Unix,
                A=procmail -Y -a $h -d $u

Should be changed to read...

Mlocal,         P=/usr/bin/protector, F=lsDFMAw5:/|@qSPfhn9, S=10/30, R=20/40,
                T=DNS/RFC822/X-Unix,
                A=procmail -Y -a $h -d $u

Second edit

Mprocmail,      P=/usr/bin/procmail, F=DFMSPhnu9, S=11/31, R=21/31, T=DNS/RFC822/X-Unix,
                A=procmail -Y -m $h $f $u

Should be changed to read...

Mprocmail,      P=/usr/bin/protector, F=DFMSPhnu9, S=11/31, R=21/31, T=DNS/RFC822/X-Unix,
                A=procmail -Y -m $h $f $u

Note that in both the above edits - not all ocurrances of the string "procmail" are changed - only where the name is supplied as part of a P= string.

NB : If your sendmail.cf is created using the "m4 sendmail.mc" logic, you will (naturally) loose these edits if you run "m4 sendmail.mc" again

Stop and Restart sendmail

Now, Stop and re-start sendmail. On linux you do it like this..

        cd /etc/rc.d/init.d
        sh sendmail stop
        sh sendmail start 

And that should be that.

If you want to know what combination of mime types protector lets through, or to add or remove some - check out the "part_filter" script.
