Hi everybody, anyone knows of a SA plugin to score mails based on challenging the sender e-mail?
I don't mean C/R, but instead just attempt an SMTP session in order to see if the source mailbox is known to the sending domain's MX. If it isn't, the plugin applies a score to the e-mail. I know I could do something like this in my postfix, but this way I would totally reject e-mails carrying a wrong From: header. Since some people seem to be a bit dyslectic in writing its own e-mail address, I would prefer not to reject unless there are some other reasons too (i.e.: the mail hits some other SA rules). Thanks, Giampaolo
