Ventura mail POP not available?

An excerpt from the following link regrind manually setting up iCloud configurations

iCloud Mail server settings

• iCloud Mail uses the IMAP and SMTP standards supported by most modern email client apps. iCloud Mail does not support POP.
• If you set up an account using iCloud System Preferences or macOS Mail in 10.7.4 or later, you won't see these settings because they're automatically configured.
• Refer to your email client app's documentation for information about how to use these settings.

Read the part about server settings where POP is mentioned.

Apple (and, I should say, the industry in general) has been driving users away from POP for years.

For a while now, there has been a hidden trick to install POP accounts.

I have not tried it in Ventura, but I expect that it may still work:

1) Create your new account, just as if it were IMAP. Enter a WRONG password

2) When asked to set your details a second time, there should be an option to choose POP. Fill in the right password this time.

Note: it is not like POP itself does not work: if you upgrade your OS, or migrate a user account that included some POP e-mail accounts, they work. I know that from experience, as I still have a POP account myself. I clean installed Ventura and then migrated my user accounts from Time Machine, and my POP account is just fine.

FWIW, you can still use the same strategy of local mailboxes, even if your accounts are IMAP or Exchange: just drag your messages to any mailboxes that are under "On My Mac".

The caveat being iCloud does not support POP configurations and hope the OP realizes this.
