Change email domain

I have mautic installed on my server, mautic.xyz.com.

I am sending from multiple domains like aaa.com, bbb.com, ccc.com.



All the 3 domains are aligned with SPF, DKIM and DMARC. All of them are passing the tests.



but when i send an email, the headers show email sent from xyz.com and even though SPF is passing , it is tagging xyz.com as spam due to domain reputation. How do i change my domain sender.

Are you using an email service, local email server like sendmail or an external SMTP server?

Use my own server which is Sendmail as SMTP.
