Domain Mail on Plesk - MX on Cloudflare Routing issue

[Datasleek]

Hi,
My mail server domain stopped receiving email since yesterday.
My registrar is godaddy Name server is Cloudflare.
Everything was working fine until this AM.
Nothing has changed server setting wise.
I can send email from UCLA domain and I receive the email.

dmarc data-sleek .com The record is not valid
blacklist mail.data-sleek .com Blacklisted by UCEPROTECTL3
mx data-sleek .com DMARC Quarantine/Reject policy not enabled
dns data-sleek .com SOA Serial Number Format is Invalid
dns data-sleek .com SOA Expire Value out of recommended range
smtp mail.data-sleek .com Reverse DNS Resolution - No PTR Record found

Hi @Datasleek, I am not certain what troubleshooting steps you’ve taken, but the suggestions in this #tutorials, Email Troubleshooting are designed to address the issue you describe.

Let us know if that helps & how it’s going.

I see that the ‘mail’ hostname in your domain is a direct connection.

@Datasleek

I can send email from UCLA domain and I receive the email.

Are you saying that your server does receive email?

For mail you don’t receive, is it being bounced back to the sender?

[Datasleek]

@sdayman
Mail is not being bounced and the mail queue on my mail server is empty. That’s why it is not easy to debug. I don’t have enough expertise in DNS management. It’s been working fine for 6 months when I was using my own DNS server and was using CloudFlare for mostly the web.
I just need help setting up the dns properly in Cloudflare

@cloonan ,
Thank you for referring the video. I have checked and my records matches the recommendation.
I did enter “@” for the name for MX record and it replaced it data-sleek.com (see attached)

[sdayman]

None of that is related to receiving email. And you didn’t answer my question:

@sdayman

Are you saying that your server does receive email?

Give this a try to watch how your mail server receives email:

@sdayman , I use mailgun for SMTP
Here is the test

[sdayman]

Ah, not to Mailgun. To your own domain at the .251 address.

[Datasleek]

@sdayman ,

I don’t use my domain to send email, I use mailgun for SMTP.
However, here is the test result.

I’m getting emails from [email protected] to [email protected]
Email from Gmail are also coming though.
Not sure why others are not working.

[sdayman]

You should probably start checking Plesk forums, as Cloudflare is not involved in this connection.

[Datasleek]

@sdayman ,
Yes I have a feeling the issue might be there too.
Quick question. Do I need to have MailGun related DNS entry in Cloudflare DNS? Since my mail client uses smtp.mailgun.org I’m not sure why I would need these extra entry?

[fritex]

Kind a lot and a bit of strange records you have got here.

So, you aren’t able to send emails from your origin or from Mailgun service?

Have you checked with Mailgun documentation already?:

Also, maybe for the CNAME record, you would just need to make sure that the status is configured as ‘DNS Only’ ( cloud)
