Hello, I'm trying to block a recipient's address (To:) but it doesn't work.
# main.cf header_checks = regexp:/etc/postfix/header_checks /^To.*gus...@gmail.com/ DISCARD warning: header Subject: test Sat, 08 Aug 2020 12:44:14 -0300 from vps-1107836-x.dattaweb.com[179.43.124.100]; from=< ggonza...@ambitecnica.com.ar> to=<gus...@gmail.com> proto=SMTP I've tried To: or to = but can't get it to work. I know this is a dummy question but I would like some help on that, thanks. Regards,
