Hi, Craig.
Remember that umask is a negative mask -- it turns OFF the
specified permission bits. (I think -- oh, always get
confused when I deal with this.) Umask interacts both with
chmod and with the mode you specify when you create the file
or directory.
It is used right-justified, as any numeric value would be, so:
022 denies write permission to group and world;
0775 denies all permissions to owner and group and
gives ONLY write permissions to world. So I don't
think you'd want to use this.
Read about umask in 'man bash' and also look at 'chmod'.
You use a .forward file to activate procmail -- I forget how.
After that the rc file will come into play.
Good luck,
Vic
