First of all you need to open the 'Settings' app from your 'Homescreen':

Then tap on 'Account & Passwords' to open the settings of the 'Mail' app:

On the next scree tap on 'Add account':

Then you will be asked to choose the provider of your account. Select 'Other' there:

You will be asked to enter your personal account information. Enter your name, the 'reply to' address and the description of the account (if necessary).

On the next screen you will be prompted to choose the account type (IMAP/POP). Choose POP there and then enter your account information provided to you (see 'Mailbox information' on your configuration papers)
