I do not wish to delve into whether these tags are useful or not, but rewriting subjects or bodies invalidate existing DKIM signatures. I recommend using separate domains, or subdomains, for regular business and for mailing lists, combined with separate DMARC policies, e.g. 'quarantine' for example.org and 'none' for mlists.example.org. -Ralph _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
