Issue Qmail error : "Failure : this address no longer accepts mail"

[J0R1SK]

Hello,

Our organization is using Google Workspace to send and receive emails with ourdomain.com.
Google needs a specific DNS config as you may know, so I added the following in the OVH parameters:

Nom/hébergeur/alias	Valeur TTL (Time to Live*)	Type d'enregistrement	Priorité	Valeur/Réponse/Destination
@ ou laisser vide	3 600	MX	1	ASPMX.L.GOOGLE.COM
@ ou laisser vide	3 600	MX	5	ALT1.ASPMX.L.GOOGLE.COM
@ ou laisser vide	3 600	MX	5	ALT2.ASPMX.L.GOOGLE.COM
@ ou laisser vide	3 600	MX	10	ALT3.ASPMX.L.GOOGLE.COM
@ ou laisser vide	3 600	MX	10	ALT4.ASPMX.L.GOOGLE.COM

When a WordPress website is installed on our Plesk server, we use the Contact Form 7 plugin but it seems that all emails from our own domain are not sent.

Here is the Qmail log I have each time:

2022-02-03 16:48:04	qmail[22200]	delivery 31: failure: This_address_no_longer_accepts_mail./

But emails are working with external domains (ex: [email protected]), it is only messy with our domain name.
Do you have an idea of the problem it could be?

I tried a lot of things but nothing worked yet:
- Changing Mail server settings
- Changing DNS Settings,
- Adding Smtproutes via the SSH Terminal,
- Checking the WP configuration,
- Checking OVH DNS settings,
- Etc.

But I guess there is something messy somewhere. If you have a clue or need more details about something, please post a comment on this post.

Thank you!

PS: I read this post before posting but it is still not solved today...

Qmail error : "Failure : this address no longer accepts mail"

Hi everyone, I have a problem since 2 days with sending emails. I do not know if this is related but I modified a DNS record there shortly (but absolutely not the MX record). Server Ubuntu 12.04 Plesk Panel 12.5.30 Log file : Jan 29 16:09:02 ns306815 qmail: 1454080142.090553 new msg...

Did you make sure that mail services for your domain have been disabled in Plesk?
Domain => Mail => UNcheck the box "Active mail services for this domain".

If mails for your domain are not handled by Plesk then you need to disable mail services for that domain, otherwise the server will try to deliver the mail locally instead of delivering it to Google

Hi Monty, thanks for your reply!

Yes this box is already unchecked, the problem is coming from other settings.

What is really strange is that personal Gmail accounts are working well with Plesk, we only have the problem with our internal Google Workspace domains + Plesk. So I guess it may be a conflict with Google deliveries?

Maybe try to run plesk repair mail on your server

Same problem unfortunately...

When I add Google Workspace DNS directly in Plesk, they are not recognized by the admin. But when I add them in OVH settings, they work.
Maybe I am missing a parameter or I have an unwanted loop somewhere...
