Hi, Speaking of Ironport. Do you know if cisco issued a Best Practice regarding Dmarc ? There's nothing in the several guides for Asyncos.

Message-ID: <[email protected]> Content-Type: text/plain; charset="us-ascii" Hi All, The DMARC spec defines a Mail Receiver as 'The entity or organization that receives and processes email. Mail Receivers operate one or more Internet-facing Mail Transport Agents (MTAs)'. Aggregate reports are generated by the Mail Receiver to provide feedback to the Domain Owner. Does this imply that the Mail Receiver is responsible for aggregating reporting data from all it's MTAs and sending back a single report to the Domain Owner? Or it is acceptable to send one aggregate report per MTA? Please help clarify this. Thanks, Lavanya -------------- next part -------------- An HTML attachment was scrubbed...

Yahoo, AOL, Google, and Hotmail each send one (1) aggregate report to each sending domain. If they can do it, surely Cisco can.

I send a report per site, not per MTA but as long as the reportID is unique, you are fine. ------------------------------ _______________________________________________ dmarc-discuss mailing list [email protected] http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html) End of dmarc-discuss Digest, Vol 13, Issue 18 ********************************************* _______________________________________________ dmarc-discuss mailing list [email protected] http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html)
