Robert did say "identical", so maybe if he can be more specific about
what "identical" means we could come up with a suggestion more
efficient than this general-purpose sif. (A better name would be
"sift", "SImilar File Tagger" ;-)
I suggest that Robert arrange that his spam-hunting recipe
automatically generate a complaint to the correspondents who are
consistently sending repeats, and get them to arrange a mailing list
instead sending dupes ... that would make the computation worth it!
By "identical" I mean "exactly the same, character for character in the
body of the message". That is, a "cmp" of files containing the bodies
would return status of 0.
And this isn't a spam specifically that I'm preventing myself from. It
happens that whoever maintains the CPSR (Computer Professionals for
Society Responsibility) mailing lists sends out the same message in two
different mailing lists. It's just a waste having to wade through messages
that are precisely the same, except for the header.
Regardless, I'll try to look for this "sif" thing.
