Setting up DNS MX Entry on Digital Ocean - email

Question

I want to use DO as my DNS Server. For emails I use 1and1 and I setup the Nameserver Configuration in the Domain control panel to use the DO Nameserver.
In DO I added an MX entry:
But is this the correct way? If I use one of my email I set up, do I need to configure it differently? If I send an email, nothing is being received in my inbox. For example the mail test#isarfaktor.de
How do I need to configure DO to handle emails with 1and1 properly?
Thank you

You didn't mentioned the Operating system of your Virtual Private Server.
First, you have to setup your server using postfix if you follow my method.
Approx 29% of public mail servers on the internet run very popular opensource mail transfer agent Postfix.Its helps to route and deliver email on a Linux system.
Make sure you have set up the domain with the ip already.
Now install post fix
sudo apt-get update
sudo apt-get install postfix
it will ask for domain name put your domain like this - farukkadir.com without any prefix like www.
now you have to edit postfix config by put this command
sudo nano /etc/postfix/main.cf
find myhostname = something.com and edit with your domain
If you would like to configuring mail to be forwarded to other domains or wish to deliver to addresses that don't map 1-to-1 with system accounts, you can remove the alias_maps parameter and replace it with virtual_alias_maps. We would then need to change the location of the hash to /etc/postfix/virtual:
virtual_alias_maps = hash:/etc/postfix/virtual
and to get a webui install open source squirrel mail -
