Configuring Yahoo.cz for an iPhone

What is Yahoo.cz:

Yahoo! Mail is an email service launched on October 8, 1997, by the American company Yahoo, Inc. It offers four different email plans: three for personal use (Basic, Plus, and Ad Free) and another for businesses. As of January 2020, Yahoo! Mail has 225 million users. Users are able to access and manage their mailboxes using webmail interface, accessible using a standard web browser. Some accounts also supported the use of standard mail protocols (POP3 and SMTP). Since 2015, users can also connect non-Yahoo e-mail accounts to the webmail client. Source: https://en.wikipedia.org/wiki/Yahoo!_Mail

Configuring Yahoo.cz:

Mail app can find the email settings itself and set up your account. Follow the following steps first in order to find out if it can:

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

In case the Mail app hasn't been able to automatically set up your account, then you need to enter them manually. I think you will need the information below:
