ARC Protocol support

Hi,
I would like to know if Zone-MTA support ARC (Authenticated Received Chain) Protocol ?
If not, do you plan to support it ?
Best,
Pierre-Yves

Ignore the random scammer :)

There's currently no ARC support. I can't tell you if there are plans for it, as I'm not involved in that, but I can tell you that the use of ARC is very limited unless you're an extremely large sender.

ARC requires the recipient to trust your ARC signature. None of the big players are going to go out of their way to trust every small email sender there is. But perhaps you have a specific use case in mind?

Hi,
Sorry for the response delay :)
In fact, one of my customers uses our Zone-MTA-based platform.
He has a postfix in relayhost to our zone-mta and he signs all his mailings in DKIM and therefore loses his signature to the final recipient.

ARC won't help with that, as far as I know. Unless there's a detail I'm missing?

I think you should focus on what is breaking their dkim signature on your platform. Unless you're modifying content that shouldn't happen.
