DKIM problem "body hash did not verify" : cannot solve it **for months**


#1

Hello,
When I send emails using my SMTP server (using mail.app macOS software), DKIM passes.
But when I send emails using PHPList configured to use the same SMTP server, DKIM doesn’t pass : I got “dkim=neutral (body hash did not verify)”… SPF pass in both situations but DKIM doesn’t pass with PHPList (DKIM pass when emails are sent with mail.app).

I try to solve it for months and I can’t have it working. I’m really tired… Could you please help me ??
I tried to compare headers of emails that I send with macos’mail.app and PHPList. Here is the DKIM differences :
mail.app DKIM OK :

Authentication-Results : ⁨mx.google.com; dkim=pass header.i=@mydomain.be header.s=default header.b=u4HMfYqt; spf=pass (google.com: domain of remi@mydomain.be designates 185.212.227.251 as permitted sender) smtp.mailfrom=remi@mydomain.be; dmarc=pass (p=NONE sp=NONE dis=NONE) header.from=mydomain.be⁩

PHPList DKIM NOK :

Arc-Authentication-Results : ⁨i=1; mx.google.com; dkim=neutral (body hash did not verify) header.i=@mydomain.be header.s=default header.b="kB/ZKeN9"; spf=pass (google.com: domain of noreply@mydomain.be designates 185.212.227.251 as permitted sender) smtp.mailfrom=noreply@mydomain.be; dmarc=pass (p=NONE sp=NONE dis=NONE) header.from=mydomain.be⁩

Hi.

Not that familiar with phplist in terms of the email/mail process.

However can you tell the list if you’ve ever gotten phplist/email to work with any other smtp provider?

If you have, can you provide the details.

If you haven’t can you setup a test gmail/yahoo account, and then test against the smtp servers from both providers?
