Setting up Fastmail.se:

Mail app may find the email parameters itself, then complete setting up your account. Follow these steps in order to try:

1. Go to Settings > Mail, then tap Accounts.
2. Click Add Account, tap Other and tap Add Mail Account.
3. Type your name (can be any name), your email address, password and a description for your account
4. Tap Next. Mail will now try and find the mail parameters and finish setting your account. If Mail finds the e-mail settings, tap Done to complete your setup.

In case Mail hasn't been able to automatically set up your account, it means that you will need to enter them yourself. I think you will find the table below useful:

Tap Next, then follow these steps:

1. Select either IMAP or POP for your new account. If you don't know which one to choose, contact Fastmail.se
2. Type the required details (You might want to have a look at the table above) for Incoming Mail Server and Outgoing Mail Server. Then click Next
3. If the email setup is correct, tap Save to finish the setup. If your mail configuration is incorrect, you will be asked to modify the configuration
4. If you still can't configure the email account, or save your settings, contact Fastmail.se.
