My site finally resolved to my new SM Cpanel server. I log into my email account via neomail and sent myself some test messages to my aol account. Every message i send stays in my queue and when i attempt to deliver, i get the errors below. Can anyone enlighten me on this or what i can do so that it stops doing it?

I can send and receive just fine from outlook (SMTP / POP3)

I think I`ll test NeoMail now....
