The reason I think this is marginally relevant to the Procmail list is
that the whole SHELLMETAS issue is basically an instance of the same
phenomenon and that I wanted to point out that this is something the
generic you should probably understand about Unix.
Quoting from the Unix programming FAQ:
: The recipients of a message can simply be specified on the command
: line. This has the drawback that mail addresses can contain
: characters that give `system()' and `popen()' considerable grief,
: such as single quotes, quoted strings etc. Passing these constructs
: successfully through shell interpretation presents pitfalls.
Is this intended as a correction, or a pointer to more information?
Perl, like Procmail, doesn't invoke a shell unless the command line to
execute includes shell metacharacters.
