Resolved Plesk Email Security issue with full hostname

[Jellab]

Server operating system version

Ubunu 22.04

Plesk version and microupdate number

PLESK Obsidian v18.0.75 (build 1800260102.11).

Hi all,

I'm new here.

After an issue I reinstalled my server from scratch with Ubuntu Os V 22..04.5 LTS
Then i reinstalled PLESK Obsidian v18.0.75 (build 1800260102.11).

Now i have an issue with emailing (sending).
I can receive emails but noithing is going out.

I noticed that the Plesk Email Security is corrupted as you can see here :


When i check the full hostname, it seems correct :


Plus all my emails are waiting in a queue and not delivered :


For information i have bought the Plesk Email Security to be in the safe side, but nothing changed.

Somebody have already this problem or found a solution ?

Try applying the steps from this support article. Afterwards also restart amavis (systemctl restart amavis), just to be on the safe side.

Hi Kaspar,
I tried what you ask me but it is too hard form me.

For the moment , I solved half way as i save the full hostname with another random one and then resave it with the correct one and then Plek Security Email work again (tips mentionned on a post somewhere here).

But all the outgoing emails are not received to an external email server (like @Gmail,.com...)

I mean i still have emails deferred!!

Hi all,

Is this meaning that the SPF, DKIM, DMARC are not configured and i cannot send emails?

The check reports that the SPF/DKIM/DMARC records are not configured. If you have recently added the records, the results might be outdated, please use the refresh button at the right to run a new check.

Not entirely. If SPF, DKIM and DMARC aren't configured for your domains, you should still be able to send email. However many providers (like Gmail) will reject your emails, because they require SPF, DKIM and DMARC to be configured. So it's highly recommended to configure those for your domain(s).

In the screenshot of earlier post it shows that messages are being deferred with the 4.4.1 status code. Which means the mail server is unable to connect to the recipient mail server. Usually because of a (firewall) blocked port. Are new messages still being deferred with the same status code?

Hi,

Sorry i was abroad.

For the moment i can send and receive emails only from inside my server.
Gmail's emails are not received.

And it seems that the SPF, DKIM and DMARC are well configured as you can see here :


So, i'm still stuck to send emails to another email server like gmail...!

see the post before, it seems all is configured.

No, they aren't. If you use a public DNS tool to check for SPF records of your domain it does not return any results. Check this result for example from MXtoolbox. It seems the DNS zone for your domain is managed directly with your provider (Contabo), not by Plesk. You'll need to update the DNS records at Contabo or have the name servers of your domain point to your own DNS servers (if you have any).

Hi,

If i understand i need to replace the ns1.vanremoorterebv.be with ns1.contabo.net?
(and for nsé and ns3).

 

[Kaspar]

You're already using the Contabo nameservers (see here). What you need to do is to add these (SPF, DKIM and DMARC) DNS records to the domain in your Contabo account.

Edit: see Contabo documentation for help
