It is incredibly easy to install Mailcow as it is distributed as a docker container. @0xDEC0DE introduced it to me so thank you to him. It only takes 15 minutes to install and get all setup. In 15 minutes you can hook your website up with it's own email server. You want to use a separate email server because you cannot proxy your mail server behind Cloudflare. In order to hide your origin IP address you cannot use your web server as your email server. There are also several things you need to do to keep your server from getting blacklisted by spam blacklists which I will teach you.

You might have to open port if firewall is running on your server. Run the following commands

1

root@mail:~# sudo ufw allow 25,80,443,110,143,465,587,993,995/tcp

Now go to browser and open https://mail.yourdomain.com with the default credentials admin + password moohoo.

mailcow-admin-login-window

Inside admin dashboard make sure to change the password.

mailcow-admin-dashboard

To add domain and user go to configuration in the top menu

mailcow-add-domain-mail-window

To access mailbox go to https://mail.yourdomain.com/sogo and enter username and password.

mailcow-webmail-login

Next screen will be something like this.

mailcow-webmail-dashboard

Final DNS Configuration

You also need to setup DKIM, DMARC and SPF record to finish the installation.

TypeHostValue
TXT@“v=spf1 mx a -all”
TXT_dmarc“v=DMARC1; p=reject; rua=mailto:mailauth-reports@example.org”
TXTdkim._domainkey“v=DKIM1; k=rsa; t=s; s=email; p=…”

To get the DKIM go to configuration>>domain>>edit as follows

add-dkim-mailcow

At the bottom of next page, you should find DKIM key. Copy it and paste it in DKIM TXT record.

dkim-key-mailcow-location
