Yes me too I used SMTP Mailer and it works, thanks to you Studiotwo.
Tried WP-Mailr-SMTP didn’t work for me.
This is what I did
Once installed the plugin,
Go to setting:
SMTP Host – mail.yourprimarydomainname.com (Not any domain name just your package primary domain name-they share the servers)
SMTP Authentication – False
SMTP Username – the name of your cpanel (primary domain name cpanel)
SMTP Password – password of your cpanel
Type of Encryption – No Encryption
SMTP Port – 25 (if you’re using wordpress) if you don’t know ask your hosting company
From Email Address – any email
From Name – Your name/company
Have Fun!
