If you forward spam (automatic forwarding), you will be listed as the spammer because even DKIM is valid. Filters on the sender won't work anymore at the destination the forwards points to. S/MIME will be applied to the forwarded messages and people will assume everything is fine even when the original message is forged. -- Gruß Marco Spam und Werbung bitte an ichschickerekl...@cartoonies.org _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
