Email Delivery Problems

[marcioralima]

Hello,

I recently purchased a VPSserver in Vultr and opted for the cPanel admin panel. The server is already configured and I'm starting to migrate my sites to this new server. However I am having problems with email deliveries.

Yesterday I received a message from cPanel stating the following:

Good news, AutoSSL has successfully renewed the Validated Domain (DV) certificate for "example.com.br". This does not require any further action by you.

Then I thought that SPF and DKIM had already been successfully installed, however the error remains.

Through cPanel I created an email account [email protected] and according to some tests I did sending to Gmail and Outlook, the emails sent by the server are going to the spam box.

So I sent an email to the service "[email protected]25.com" and it returned with a detailed analysis of errors that are occurring in the SPF and DKIM records, which is probably causing the message delivery problem.

I have 3 panels where I can configure the DNS of my domain. The Vultr panel, the WHM panel, and the cPanel. In the WHM panel there are 15 records, in the Vultr panel there are 7 records and in the cPanel panel there is apparently only 1 MX record. Does cPanel consider WHM records or is necessary to enter this same records in the DNS Zone Editor in cPanel? And in the Vultr server panel, do I need to insert the same records as in WHM?

Here is a summary of the test in verifier.port25.com:

================
Summary of Results
================
SPF check: none
DKIM check: permerror
SpamAssassin check: ham

================
Details:
================

HELO hostname: cp.example.com.br
Source IP: xx.xx.xxx.xxx
mail-from: [email protected]

-------------------------------
SPF check details:
-------------------------------
Result: none (no v = spf1 record published)
Verified ID (s): [email protected]

DNS record (s):
Powered by Blogger. TXT (no records)

-------------------------------
DKIM check details:
-------------------------------
Result: permerror (not usable key records)

DNS record (s):
default._domainkey.example.com.br. 300 IN CNAME example.com.br.

DKIM Results
============

permerror: The message could not be verified due to some error that
is unrecoverable, such as a required header field being absent. A
later attempt is unlikely to produce a final result.

SPF Results
===========

none: Either (a) no syntactically valid DNS domain name was extracted from
the SMTP session that could be used as the one to be authorized, or
(b) no SPF records were retrieved from the DNS.

How I can fix it?

Thank you.

Hello,

Is this domain name using name servers associated with the cPanel server, or with the remote DNS service provider?

Thank you.

Thank you.

Hello,

It is attached as are the DNS in Vultr, WHM and cPanel.

Thank you.

Hello,

DNS records configured on the cPanel server are not automatically synced to remote DNS providers. You'd need to manually configure all DNS records for the domain name via the remote DNS provider's administrative interface.

Thank you.

Thank you man, the problem has been partially resolved because Hotmail/Outlook remains with the emails going to the spam box. Gmail and Yahoo are ok.

See the new tests with the new records added in server panel:

==========================================================
Summary of Results
==========================================================
SPF check:          pass
DKIM check:         pass
SpamAssassin check: ham

    mydomain.com.br. 14400 IN A 45.77.xxx.xxx


----------------------------------------------------------
DKIM check details:
----------------------------------------------------------
Result:         pass (matches From: [email protected])
ID(s) verified: header.d=mydomain.com.br

How can I fix this problem with Hotmail/Outlook?

Thank you.

Hello,

If you are already following the guidelines referenced on this document, and email to remote mail servers such as Hotmail still goes to the SPAM folder, then the next step is to contact the remote mail server's support team to see if they can provide more information about why your messages are marked as SPAM (in some cases it's simply due to the past reputation of the IP address). For instance, Hotmail provides the following troubleshooter:

Thank you.

I have some issues in the delivery while I am using my own websites email ID hosted on cPanel
my website is Domain.com and it is hosted with another website as the main domain on cPanel. Created a webmaster email [email protected] but when sending it never finishes.

@supkillgill - I removed the domain name from your post for security reasons, but if you check your IP address at Email Blacklist Check - IP Blacklist Check - See if your server is blacklisted you'll see you are listed on Barracuda, which is a major blacklist. That would explain why email is not reaching your destination at various providers.

You may need to work with your hosting provider to have them help get you removed from that blacklist.
