How to change outgoing "Mail From" address

[wizardcomputers]

I am running into some issues with all my client domains that I have access to my CWP server as all emails sent from the website which is hosted on there account are going to the SPAM folder or being Rejected.

I want to know how do i change the "mail from" address on each CWP User account, so that is matches their domain.

Current the mail from address is user account @ the server name (eg user2@my.hostingservername.com), but I want the mail from address to be what the actual clients real email address which is info@customerdomain.com.

Based on the research i've done, this is the reason why SPF Alignment fails and results in the DMARC test failing as well


Any Help or advise greatly appreciated.

Client applications should use SMTP not sendmail and authenticate with their own domain email address. Sorted.
