Greetings,

Thank you for asking.

I am sorry to hear you are experiencing an issue with receiving and/or sending e-mails while using Coudflare for your domain name.

Usually, the MX record should point to a hostname such as mail , and the A (or CNAME ) type record for that hostname should be set to (DNS Only).

I use wordpress and mailgun.

May I ask is the WordPress / hosting server IP sending e-mails? Have you configured WordPress to connect to mailgun and send emails via mailgun, rathert than from the web hosting IP?

Kindly, I’d suggest you to try below plugin as far as it works perfectly for WordPress, just configure it to use your e-mail provider with the credentials:

WP Mail SMTP by WPForms

• tick the checkboxes the “Force name” and “Force email” → How to Set Up the Other SMTP Mailer in WP Mail SMTP

Can you share your domain name just in case we would have to check if the SPF/DKIM/DMARC records are in place?

Furthermore, if you recently moved your domain to your Cloudflare account, I could try to troubleshoot at first sight without knowing anything other as it could be related to either:

1. Wrongly setup e-mail related DNS records at the DNS tab of Cloudflare dashboard for your domain name
2. Possibly missing some TXT/CNAME records (for SPF, DKIM, DMARC if so?)
3. You are using a hostname like yourdomain.com which is (proxied) rather than the unproxied (DNS-only) like mail.yourdomain.com (possible this one not existing or is instead of being ) at the DNS tab of Cloudflare dashboard, in your e-mail client for sending/receiving server (MS Outlook, Mozilla Thunderbird, etc.)

May I suggest checking below article if your e-mail records (usually the A mail and the MX record) are configured properly while you are using Cloudflare for your domain name:

I would also recommend looking into the below article due to further prevention of your e-mails being marked as a SPAM at the recipient’s side:

How to prevent your emails from going to spam

As a website admin, you will likely be sending out emails to your customers or visitors for newsletters, account notifications, product updates, etc. Depending on the circumstances, you might start noticing your emails are ending up in customers’ spam/junk folders instead of their email inbox. This issue can be caused by a few things, and I’ll go into detail for each: Misconfigured DNS/absence of necessary records Poor domain reputation FAQ Misconfigured DNS/absence of necessary records For…

Nevertheless, using online tools on the links below you could test and troubleshoot more what is going on with your e-mails:

Sharing here a list of websites/tools I usually use to check, test or even generate something in case I forgot how does it go: https://toolbox.googleapps.com/apps/dig/ https://ssl-tools.net/ https://ssl-tools.net/mailservers https://ssl-tools.net/mails https://www.checktls.com/TestReceiver https://www.mail-tester.com/ https://en.internet.nl/test-mail/ https://intodns.com/ https://powerdmarc.com/power-dmarc-toolbox/ https://www.immuniweb.com/ssl/ Hope they will help you too

Otherwise, you might have to troubleshoot if the port like 110/143/993/995 and 25/465/587 is open at your hosting provider and contact hosting provider to check this for you. If they are not open, then I am afraid you may not be able to receive any emails from using that web hosting/email provider.
