To setup push mail on your iPhone, iPad or iPod touch, go to Settings -> Mail, Contacts, Calendars -> Add Account
Choose Microsoft Exchange and supply your email, username, password and account description.
Click next and after some verification you will be back at the same screen, but this time it will ask a server from you as well. For the server enter moses.innernethosting.com and click next again.
On the next screen make sure mail is on and add Contacts if you want to use contacts on the server as well. (Do not delete contacts on your phone if you are not sure you want to do that). Select Save.
Select the new account that you just created, then select the email address to enter the mail settings. Go to the bottom and unselected Use SSL.
Back at the account screen, change the Fetch New Data option to Push.
For Android the setup is similar.
Send a test mail to make sure your account is working.
