 BullMail is a no-bullshit solution to setup an E-Mail server on a Debian/Ubuntu shitbox.
 
 ## Now updated to work with Debian 13 Trixie
-If you ran this script before, simply run it again. Just a heads up, it will generate new DKIM keys. I recommend you generate new ones otherwise this shit might break.

 Now, you want to point these records in a way that `mail.yourdomain.com` resolves to your server's IP.
 
+Now, make sure to also add this TXT record (this TXT records have no name. Input `@` if it forces you to put a name in):
+```
+v=spf1 mx a:mail.yourdomain.com ip4:51.79.70.119 ip6:2607:5300:205:200::35c2 -all

+```
+v=DMARC1; p=reject; rua=mailto:postmaster@yourdomain.com; fo=1

+Lastly, add this `MX` record to your domain:
+```
+mail.yourdomain.com

 **Keep your domain's DNS manager open, we're not done with it.**
 
 ## Step 2
 Go to your host's server configuration panel and set the rDNS (Reverse DNS) to `mail.yourdomain.com` (obviously, replace `yourdomain.com` with your own). This helps some exotic mail servers to perceive your E-Mails as not spam. After setting up the rDNS, restart the server and run this from your local machine:
 
-```
+```sh
 will@fuckedmachine:~$ ping yourdomain.com

 ## Step 3
 SSH onto your shitbox and become root
-```
+```sh
 sudo su

 ## Step 4
 Create your mail user. Note that all users with the `mail` group will be able to send and receive mail.
-```
+```sh
 useradd -m yourname -G mail
 passwd yourname
 ```
 
 OR... If you already have an user that you use (say, `will`), do this instead:
-```
+```sh
 usermod -aG mail will
 ```
 `-aG` tells your stupid server "hey, `mail` is a secondary group for `will`!" `-G` says it's the primary group.
