Happy new year!
I have encountered a problem of which i’m not sure where to look for the solution: an email, - sent through a SMTP plugin in Wordpress (with Contact Form 7) - is successfully being sent to the recipient -but- the copy to itself ([email protected]) holds the following error:
This is the mail system at host outbound5.mail.transip.nl. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <[[email protected]](mailto:[email protected])>: host mail.my-client.nl[my-vps-ip] said: 550 smtp auth required (in reply to RCPT TO command) Reporting-MTA: dns; outbound5.mail.transip.nl X-Postfix-Queue-ID: 4Nm8rz1JfyzHQrp X-Postfix-Sender: rfc822; [[email protected]](mailto:[email protected]) Arrival-Date: Mon, 2 Jan 2023 22:58:59 +0100 (CET) Final-Recipient: rfc822; [[email protected]](mailto:[email protected]) Original-Recipient: rfc822;[[email protected]](mailto:[email protected]) Action: failed Status: 5.0.0 Remote-MTA: dns; mail.my-client.nl Diagnostic-Code: smtp; 550 smtp auth required
Is this something within HestiaCP not sending the auth details? I’m sure that those are correctly setup in the SMTP plugin.
If I take a look at the exim mainlog it shows:

Thanks in advance!
