Whether a message passes DMARC or not depends on the From: address in the email headers. Unless you rewrite that (which looking at the archives it doesn't appear you do) you'll see rejections from some sites if that domain publishes a p=reject policy. Could it be due to that? _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
