Setting up fast-mail.org:

It is possible that the Mail app will find the parameters automatically and complete setting up your account. Follow the following steps first to try:

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

In case Mail couldn't automatically set up your account, then you have to enter them yourself. I think you may find the information below useful:

3. If your e-mail setup is correct, tap Save to complete . If your email setup is incorrect, you will be asked to modify the configuration
4. If you still aren't able to setup your email account or save the e-mail settings, contact the e-mail provider.
