Re: Why is there a punctuation "rule" ?

Thanks for the reply.

My source has this:

      # Check for embedded brackets, parens, quotes, slashes, pipes 
(doublequotes are used at yahoo)
      if ($tstr =~ /[<>\[\]\{\}\(\)'"`\/\\\|]/) {
        $ctx->setreply("501", "5.1.7", "Malformed envelope from address: 
invalid punctuation characters");
        return SMFIS_REJECT;
      }

so clearly it is going to fail what the RFC allows.

I suppose it could be to prevent those characters from hosing the database 
commands?

I may have to edit the = and /  out of my source since I keep bouncing good 
mail that my users want due to that rule.
