send emails from accounts not hostname

I couldn't change or modify my WHM configuration to let accounts send emails from their own address like info@accountname.com (enabled SPF and DKIM) not from hostname (accountname@server1.example.com) so ALL emails go to spam for every mail provider!!

I tested many solutions like PHPmailer and set "FROM address" , "From Name" , "Return PATH" etc but made no affect .

How can can set this configuration?

Thanks

 

I sent an email with SMPT

Thanks
I sent via SMTP . It solved the issue of sender name (accountname@server1.example.com) to (info@accountname.com)
But still all emails go spam! Even with DKIM and SPF

 

Hi
I have reviewed everything and done every solutions. All emails go to spam from my server
my IP and Domain is not listed in any blacklists
I created a new domain in WHM and send an email from that domain to a new email created in AOL and Outlook. unfortunately both received in Spam box!!

Neither outlook team nor server providers know why my emails go spam!
at the end I used 3rd party email sender . It's no fair!

Thanks
