So I have a mail server set up in my homelab, and I am able to send and receive emails via
<user>@mail.domain.com. The only issue is that all my email goes to the spam folder as my IP is blacklisted from a majority of email providers. My thoughts are to create a proxy server on a VPS that has some trusted IP blocks and forward that traffic to my local server.
Is there anything that requires special consideration? I am already planning to RTFM.
FWIW I’m using umail and NGINX with let’s encrypt for the email and plan on using NGINX for the proxy as it’s what I’m familiar with (although I am open to changing this if there’s a good reason).
