Return path empty, therefore, dynamic SPF lookups based on client HELO domain?
So you're saying that the alias should work just fine? Have you checked this and this? Together with this solution? It seems it is a problem that can happen with SPF enabled. I can also reproduce the issue as I mention in the Stack Exchange post.
There are 2 suggestions in that Stack Exchange topic. One is to use BCC maps, that seems odd to me as a fix. Is that a valid approach? The other one is to use https://github.com/roehling/postsrsd, which may seem more valid. But is an extra milter really needed? Isn't this something Postfix can handle itself? I'm fishing for some more detailed advice and to validate the already given suggestions.

Postfix: How to set envelope-from when forwarding mail?
I use PostSRSd. This implements Sender Rewriting Scheme. The envelope-FROM is rewritten to an address on your own domain — so recipients will look at your SPF record, not the original sender's record. Bounces back to that address are forwarded back to the original sender. The address includes a cryptographically-generated tag to prevent this send-bounces-back channel from being an open relay.

Is it right to blame Google/Yahoo for deprecating an email forwarding service?
Documentation for ARC is pretty sparse.
The instructions for setting it up in Exim (default MTA on Debian systems) can be found here: https://github.com/Exim/exim/blob/master/doc/doc-txt/experim...
(AFAICT, there is absolutely no mention of ARC in the main Exim documentation: https://exim.org/docs.html)

Best alternative to on-prem Microsoft Exchange
EXIM is a popular option, though it seems to be subject to just as many vulnerabilities and exploits as exchange is.. so either way you go make sure to patch regularly

Looking for an email client with support for tags
I can either direct particular addresses to a mailbox on the VPS where they can be retrieved with POP3, or can forward them to any arbitrary address. Or anything else I can configure exim to do.
