I think the problem was the fact that your .procmailrc file was groupThe obvious question being: How the hell did my e-mail account get set up so that anybody with any ssc.wisc.edu account could step right up and have copies of my incoming e-mail resent wherever they wanted, whenever they wanted? Do I have some freaky technologically-inclined stalker in the department? Am I the target of research espionage? Is the department monitoring exactly how much of my time I spend doing e-mail?
writeable (mode 664). Not many people have their umask set up like
that, and procmail is very security conscious--it'd be possible for
someone other than you to direct your mail anywhere with those
permissions. I changed the permissions on the file, I think that should
fix the problem.
I know I didn't do this, since I have the airtight alibi of having only a vague idea of how to set UNIX permissions and no idea what the .procmailrc file or a "umask" is.
