Authenticated Received Chain (ARC)

[sdonovan123]

I was reading about the newest email protection standard.  Can you say if this will be implemented on the IronPorts?

Thanks!

ARC support is planned to be included in upcoming releases in FY 24 (this is subject to change)

Still no news for ARC support ...

Starting Feb 2024, Google Includes ARC in Email Sender Guidelines: https://powerdmarc.com/google-arc-sender-guidelines/ and https://support.google.com/mail/answer/81126#zippy=%2Crequirements-for-all-senders

We now urgently need ARC support on ESA !!!

Are there any documented updates on CISCO supporting ARC? Google and Yahoo have already started implementing the restrictions mentioned in the above post and we are now bouncing email forwarded to these domains.

If Cisco can't do ARC implementation this is probably end of the line for us and the ESA. We have had them since they were Ironports.

I totally agree with you: Email authentication has evolved and the new requirements from Google and Yahoo must be available urgently on ESA. Regarding this I question myself : "is Cisco still a major actor in email security ?" and "is there still any one at Cisco that still understand how actual e-mail authentication works ?"

15.5.x released recently. I guess 15.8 tentatively targeted for next quarter of 2024 (my expectation is September-October).
