Shopping Cart not sending email

Hello. Today I moved my site over from another webhost with out too many problems. However, now my cart, Abante 1.2.3 will not send email from the "contact form" or when there is a new order the customer does not receive a confirmation email. I didn't have this problem with the previous webhost company. I see that this is a Php mail issue I think. I see from another help page that Inmotion requires you to use SMTP now to send email because of spam reasons instead of the cart default "mail" option.

From this page: "https://www.inmotionhosting.com/support/email/send-email-from-a-page/why-wont-my-php-app-send-mail" it suggests:
Hostname: localhost OR mail.yourdomain.com
Authentication: Yes
Username: [email protected]
Password: Your email password
Port: 25 / No SSL
or Port 465 / SSL

I entered into Abante cart mail this setup plus port 465 and SMTP timeout at 5. Didn't work.
I also changed localhost to my server "secure183.inmotionhosting.com " Still nothing. Tried port 25. Same, nothing. I'm using my Cpanel mail which is working fine on this host and will webmail. It receives mail just fine from other sources besides my site.

In the error log I get these messages
2015-11-10 13:32:25 - Error: EHLO not accepted from server!
2015-11-10 13:32:25 - Error: AUTH LOGIN not accepted from server!

2015-11-10 13:32:25 - Error: DATA not accepted from server

Etc.. Any suggestions?
