Hello, I get spams that have an 'Envelope-From' (Sender, or equivalent attribute) different from the 'From' header contained in the mail. The spam sets the 'From' in the header to an (existing) internal user.
If the spammer would have set the Envelope-From to an internal user as well, he would have been blocked, not by Spamassassin, but by the MTA (Postfix), where I set the list of IP allowed to send mail as an internal user. Is there something implemented in Spamassassin to test and prevent mails that come from 'outside' that have the header 'From' set to an internal user? Thanks for your help, Lior -- View this message in context: http://old.nabble.com/Comparing-the-envelope-from-sender-to-the-body-from-to-prevent-fake-local-users-spams--tp27026836p27026836.html Sent from the SpamAssassin - Users mailing list archive at Nabble.com.
