I’d like to hide behind the service that I’m paying for without incurring extra fees for retaining it all. I can figure out the pull side by using fetchmail or something to a server that hosts dovecot, but the sending side is confusing since I’d need something that can receive my email and send it via the service. It’s only 1 email address, so I’m not looking for a mail relay, but something like a full caching mail proxy.
I think this is exactly what I’m looking to do. Thanks for such a detailed writeup!
I did some reading last night and think it lines up with what you’re saying. I found docker-mailserver with some configuration. The only thing I need to add is mail filtering to folders and I think that’s included.
