Hi Ken,
yes - thank you. I will then go with Complaints-To: [email protected] - even though havent seen this header in the wild anywhere so far.

Also web hosting providers and commercial SMTP services (like you) tend to add a few custom headers to identify specific subscribers. It's not universal by any means but I'd recommend it for the service you're offering. And, to to be fair, RFC 6648 (which is a best practice not a standard) depreciates the use of the "X-" prefix in favour of general meaningful custom headers (e.g. Complaints-To) so doing that is probably better. Does that answer your question? Ken. _______________________________________________ mailop mailing list [email protected] https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
