I have a private @gmail and a business @company.com (also via gmail), which I heavily rely on. Due to a recent data-leak somewhere, I'm now receiving unstoppable spam on my @gmail, and decided to set up a new account on proton and ditch @gmsil in favor of @example.com. I came across SimpleLogin, and thought that I could use that instead of protons custom domain feature for both @company.com and @example.com
Since I also host some stuff myself, I went through the self-hosting process of SimpleLogin, which was a pita dealing with postfix. But now, everything is running fine and I can send/receive @exampke.com emails, which I tested with @gmail and @company.com (gmail).
Even though it was a nice learning experience, I'm starting to wonder whether my setup is future proof and reliable, especially when it comes to spam. I really don't want my @company.com mails to land in customers spam folders.
So my question is, how reliable is a self hosted email-forwarding solution, and how does it compare with a self-hosted mail service. Like, are these two equal in terms when it comes to precautions etc?
In my experience self hosting email it has pretty much been “set it and forget it”. I feel like there’s a lot of fud from people with misconfigured email servers (because there is a lot that can go wrong on setup). In every case I’ve seen where people are complaining about email deliverability I’ve found that they haven’t configured DKIM or rDNS properly. That doesn’t mean there can’t be issues, and I am sure it is technically possible to get sent to oblivion, but I feel like this issue might be somewhat overblown.
