Running SL behind an existing mail service about app

Thanks for your quick answer.
I will consider your points and check how my mail sending will behave over time.

Thanks for your kind words! We do help running the server in the Enterprise tier (cf our pricing page https://simplelogin.io/pricing/), this is targeted towards companies who want to have their own server but individuals (or rather a group of individuals) can also opt to use this option.

Here are the answers to your questions:

1. The configuration that we recommend in Postfix is quite strict and avoids the server from becoming an open relay. You're absolutely right that running a mail server is not easy. Running one for personal use is not too difficult though as you will be less a target for attacks.

2. The mail server requires a static IP as IP plays an important role in email delivery score. The delivery score also increases with time so some initial emails might fall into the Spam/ folder. Don't worry, as long as your server is not an open relay and the IP or domain is not blacklisted, most of your emails will not be put into Spams (0% spam score doesn't exist though as how Google/Microsoft detects spams is still a mystery)

3. A small server (1-2GB of Ram) should be enough to run SimpleLogin. We are actually running several small instances in our development environment and they are running fine :).
