Hi Zhang

Are there any plans to enable native DMARC and ARC support in RedMail EE, and is there an estimated timeline for this?

Additionally, since Rspamd is widely considered the most production-ready and proven project for modern authentication, I’m considering it as an alternative. Have you or anyone in the community successfully integrated Rspamd into the current EE stack—either as a full replacement for Amavis+SpamAssassin or as a side-by-side solution specifically for ARC/DKIM signing?

I’d love to know your thoughts on the viability of this...

Thanks a lot and have a great day!
