This script installs an email server with all the features required in the modern web.
I’ve linked this file on Github to a shorter, more memorable address on my website so you can get it on your machine with this short command:
curl -LO lukesmith.xyz/emailwiz.sh
When prompted by a dialog menu at the beginning, select “Internet Site”, then
give your full domain without any subdomain, e.g.
I’m glad to say that dozens, hundreds of people have now used it and there is a sizeable network of people with email servers thanks to this script.

While the script enables your mail ports on your server, it is common practice for all VPS providers to block mail ports on their end by default. Open a help ticket with your VPS provider asking them to open your mail ports and they will do it in short order.
At the end of the script, you will be given some DNS records to add to your DNS server/registrar’s website. These are mostly for authenticating your emails as non-spam. The 4 records are:
emailwiz.shand thus must be added after installation.
They will look something like this:
@ MX 10 mail.example.org mail._domainkey.example.org TXT v=DKIM1; k=rsa; p=anextremelylongsequenceoflettersandnumbersgeneratedbyopendkim _dmarc.example.org TXT v=DMARC1; p=reject; rua=mailto:email@example.com; fo=1 example.org TXT v=spf1 mx a: -all

your VPS provider, and should set it to
mail.yourdomain.tld. Note that you
should set this for both IPv4 and IPv6.
Let’s say we want to add a user Billy and let him receive mail, run this:
