[mueenulit]

After successfully setting up Cloudflare for my site, my emails is not working any more.
I read an tutorial on community , but not understood anything ! Because I’m noob !
My Domain: sureans.com

[Neeraj_1]

There is no MX Record Found for this domain only the MX Record Found is 0:imap.sureans.com.

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.

@mueenulit

sureans.com

When I do a lookup, I can see you are using multiple different hostnames like mail, imap, pop and smtp (3rd-party email provider) as a CNAME setup.
Some of them are proxied and , others (DNS-only).
Kindly, share a screenshot of your DNS tab of Cloudflare dashboard for your domain name, but please consider masking/hiding the IPs (redact the data) due to the privacy concern.

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).

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:

Email Troubleshooting

This tutorial covers the steps you should take if, when you change your domain to point to Cloudflare, you no longer receive emails to your domain. If you follow this tutorial and still need further help, please let us know what you have tried and share your domain name and, if possible, a redacted screenshot of your DNS records in Cloudflare.

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 your 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.

Thanks for your response ! Actually I’m noob !
I’m seeing 200+ Records in my DNS tab !
Should I remove some of them?
I just have 13 subdomain !

[mueenulit]

Actually I changed my hosting multiple times!

[Neeraj_1]

@mueenulit

200+ Records in my DNS tab

It’s Depends on the sevice you have .

[mueenulit]

Currently my site is hosted on 20i Web Hosting !

@mueenulit

I’m seeing 200+ Records in my DNS tab !

Are those A-Z?
Maybe because you have had a wildcard * (apex) hoistname at your hosting provider before you added your domain name to your Cloudflare account.

@mueenulit

my hosting multiple times

@mueenulit

Currently my site is hosted on 20i Web Hosting

Okay, can you determine which one is your current hosting provider and have you got some e-mail alias/mailboxes configured within?, also I assume the company is your web hosting/e-mail provider too?

Nevertheless, take a look at the DNS of your current hosting and re-check the entries related to e-mail like A mail.sureans.com and MX record.
Therefore, following the instructions from my first post, you re-check and in case if some is missing, add the missing one (or not) DNS records under the DNS tab of Cloudflare dashboard for your domain name.

Adding DNS Records

This tutorial covers adding general DNS records and specifically A, AAAA, CNAME, MX and TXT records. Go to the DNS app of your Cloudflare dashboard. Enter your credentials and click ‘Log In’ Click the domain in question Click [image] [Please note, the content of the records below are solely for example purposes and should be replaced by valid records with content provided by your web host] Please select which record you need help adding:

Editing DNS Records

This tutorial covers editing DNS records. Go to the DNS app of your Cloudflare dashboard. Enter your credentials and click ‘Log In’ Click the domain in question On this page, you will see a list of the DNS records for your domain. This page is where you edit them. You will see the list of records like this: [DNS Page] You can click the edit button to the right of any record to change it, then click ‘save’ when you’re done. There is also a tutorial on Adding DNS Records Tutorial Refer…

Everything else is already stated in my first post how to properly configure your DNS record related to e-mail to make sure it works while using Cloudflare for your domain name.

• make sure there is an existing A mail pointed to the IP address of your web hosting provider and it has to be (DNS-only), therefore MX sureans.com should have got the target/be pointed to mail.sureans.com
• in your e-mail client, use mail.sureans.com for receiving/sending server (POP3/IMAP/SMTP)

Follow the instructions in above mentioned articles and you are good to go

[mueenulit]

Thank you Boss ! For your detailed guide ! I forgot to add a MX Record ! Just added !

Should I wait few hours ?
I’m getting following error , when sending mail to my webmail address !

@mueenulit

when sending mail to my webmail address

I am afraid I do not understand this and this error you got seems not to be related to Cloudflare

Maybe you are missing TXT records for SPF, DKIM and DMARC.

Or your message is blocked due to your IP?, or @domain being on some public DNSBL / RBL.

Or you are using wrong configuration at Gmail to send out e-mails from your domain/account.

Check this with tools for e-mail testing from my first post.

@mueenulit

I forgot to add a MX Record

UPDATE:

When I do lookup MX for sureans.com I got:

• _dc-mx.c5773c8fcc17.sureans.com.
• _dc-mx.77bc98ac4a7a.sureans.com.

Third luck, kindly re-check your A mail and make sure your MX points to unproxied DNS record (DNS-only).
An MX record should point to a subdomain, such as ‘mail’, and the “A” record for that hostname should be set to DNS Only.

Share a screenshot of your DNS tab here, but please mask/hide the IPs due to the privacy concern (redact the data).

Good!
I can see you are using 3rd-party email provider.

@mueenulit

Please assist me

1. Records A email, A mail1, A mail2, A maila, A mailboxes, A mailb, A mail-in, A mailserver, A sftp, A webdisk, A ssh - edit each and switch from to (DNS-only)
2. Remove record A mx
3. Remove record AAAA *
4. Either remove record A www.mailboxes → this won’t work without using Advanced Certificate Manager at Cloudflare due to the issue as described below, otherwise purchase ACM from the link above:

This tutorial covers a possible reason for the SSL_ERROR_NO_CYPHER_OVERLAP and ERR_SSL_VERSION_OR_CIPHER_MISMATCH errors (Firefox and Chrome respectively) when seen on a subdomain. The Cloudflare universal certificates cover example.com and *.example.com. This means that it covers any subdomain one level below the domain you signed up with. It will cover www.example.com and subdomain.example.com, as these are one level below the root domain, example.com. The certificate will not cover www.sub…
