About 70% of my spam these days contains links to Google Forms. I've been googling for tips on how to reject such email but Google find hits for the converse. (People are complaining about Gmail blocking Google Forms which is ironic.)
My current configuration doesn't include SpamAssassin since rbls and the existence of a reverse pointer was good enough. I'm looking for advice specifically to bounce email that contains a link to any Google form. If this is inappropriate for this list serve then I'm fine with the moderator nuking the request. I can take it up with stackexchange but it had been my experience that the postfix list has the best gurus.
