Might want to check out addy.io. It's a managed service, but I think it supports your use case.

I'm old school, and would set up Fetchmail. It can pull down either POP or IMAP (I haven't used POP in 25+ years, but I guess it works fine still). Then I'd run Dovecot or some other IMAP server on my host to read mail from there.

Best option is probably to look for providers that support custom domains, so you can point your domain directly to their mail servers. This usually require a paid subscription. Upside is that you retain control over your domain without having to host any email server.

The problem is that by putting a mail relay in between, while technically possible will break the SPF and DKIM chain for all emails that you forward. I don't think there is a good way around this since they check against the senders domain (and assuming that you can't get the email provider to trust your relay server)

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

I'm using Zoho to host my emails for my custom domain (I pay like $15 per year or something). I do have DKIM, SPF, and DMARC configured, as they're not hard to configure, as they're literally just a couple of DNS entries.

Moving to another provider would just be a matter of changing these DNS entries along with your MX record to point at your new provider.

Oracle Cloud has their Email Delivery service, which is basically just a straight SMTP proxy, and it's free. I believe proxies still need to be configured as a sender in SPF and have their own DKIM signing key, but Oracle will still send without them, although wildcard senders will require them.

Your basically setting up and email server with a gateway service for inbound and outbound mail delivery.

This is typically called a secure email gateway. I’m not sure if there are any designed for personal use.
