Can't set up Citadel MX Records - No mail coming or going!

Posted December 1, 2014 5.1k views

So i can’t for the life of me figure out how to set up an MX Record for Citadel, At the minute it’s not sending or recieving any mail besides internal mail coming from the same domain (so tom@deadlyllama.com can send messages to ash@deadlyllama.com, but can’t send messages anywhere else).

Then i derped and realised i need an MX Record to get the mail, the only problem is i have absolutely no idea what i need to set up to actually get Citadel mail working.

Can anyone help me?
My domain is deadlyllama.com

Assuming that your mail server is on a droplet that deadlyllama.com resolves to adding the following MX record via the DNS section of the control panel should get basic mail services working.

MX 1 deadlyllama.com

This just tells clients that mail services for your domain are handled by the server at deadlyllama.com.

This will only get a basic setup going and you will want to look into setting up an SPF record and ensure that you have a properly configured PTR (reverse DNS) for your droplet to help prevent messages you send from being flagged as spam.

    I did notice that my droplet didn’t have PTR records for a long time but i’ve just been reading into it and now something’s actually displaying there. an SPF Record i’ll set up later once i’ve got basic mail coming in and out.

    Presumably all i need to do now is wait for DNS to update?

    Yes. It may take a bit for your new DNS records to propagate throughout the Internet. Once you are ready to set up your SPF record this tutorial will help with the process.

    A carefully tailored SPF record will reduce the likelihood of your domain name getting fraudulently spoofed and keep your messages from getting flagged as spam before they reach your recipients.
