No Body-Text with Attachment

[saturnus69]

I use PHP 8.1.7 and PHPMailer 6.6.3.
As soon as I send an email with an attachment I get the email without body text and the attachment (PDF) cannot be opened. The path is correct, the PDF too.

$mail->addAttachment('../stuff/uploads/pdf/1408_dossier.pdf','1408_dossier.pdf');

Without attachment I receive the e-mail correctly.
These problems do not occur when I use PHPMailer 6.1.8.
Does anyone know where the problem is?

Can you share your code and an example of a received message? Is addAttachment returning true?

[saturnus69]

I don't know anything about this technically. Not much has changed.
SMTP Error: The following recipients failed: myemail@example.ch: sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
Interestingly, it works with version 6.1.8....

Can you show the full debug output with 6.1.8?

So it doesn't work with 6.1.8 either?

Do you have some credentials you can put in, like this:

$mail->Username = 'username';
$mail->Password = 'password';
$mail->SMTPAuth = true;

Yes, it works with this version, but not newer then 6.1.8. I dont have this informations at this time, sorry.
think i keep the working version. I go home now. Thank you for your time and help. I appreciate that. :-)
