Setting up email on iPhone

Setting up your email account on an iPhone is pretty straight forward. It can be really frustrating if you don’t put the right information in or forget a step. The biggest problem we see is the ability to send email.

Enter account settings directly into your iPhone.

If this is the first account you’re setting up on the iPhone or the iPod Touch, tap Mail.
Otherwise, from the Home screen choose Settings > Mail > Accounts > Add Account.

Choose your email account type.
For setting up email to work with your or domain mail service – Choose Other.

Tap Save to save the entered information

Upon successful completion of the mailbox you are taken back to the Mail Settings Screen.

Caution – IMAP leaves a copy of each email on the server. If you have POP set up on another device or computer, that unit will download the email off the server. If that device pulls the email, those will not be available to your IMPA device. To learn more about POP and IMAP – click here.

If you use IMAP you may find your email box getting full and incoming emails will bounce back. be sure to check your email on the server via web mail periodically – You will find the Web Mail link on the home page. Additional email space is available – See our pricing page


Additional Help

Castles email servers are not open relay servers. That means you have to be an authorized and approved user to access and relay an email through the server. We authenticate every user with both the full email address and the password.
