We continue to run into issues when emails are forwarded (especially to Google/Yahoo addresses) using the mail forwarding settings in Plesk. There's already a lot of discussion on this with no complete resolution, it seems. We have correctly set up and can verify DKIM, SPF, DMARC authentications, so they're passing for the most part. However, when an email is forwarded in Plesk using the forwarding setting for a given email address, it appears that Plesk is either re-encoding the content or changing something, which causes the body hash to not verify, even though ARC sealing is functional.
I was wondering if anyone has successfully used an alternative way to forward emails. For instance, as an alternative method, (someone please correct me if I'm mistaken) the webmail filters (forward feature) treat the incoming message as a new message to send out, instead of ARC sealing and relaying the message directly. If that's the case, it would certainly help with authentication on Google's end. Unfortunately, we currently have Horde and the script error causes this filter to not activate. The only suggested solution I've found is not doable on our end.
Any other suggestions on making sure emails forward to Gmail/Yahoo accounts successfully would also be most welcome.
Thanks in advance!
