FAQ: Send and receive Email via SMTP does not work

Many email providers require the use of app passwords when accessing their services through third-party software. If you need to use SMTP or POP3 (or IMAP) to access your email, you will need to generate an app password specifically for that software. To create an app password, you will need either the provider's app or an authenticator (like Google Authenticator) to confirm the code after enabling two-factor authentication.

App-Password should be activated as follows:
1- In the Email-Provider, activate two-factor authentication
2- Authenticate your password with the Provider's app or another authentication method
3- On the Provider settings page, you can enable App-Password
4- Make sure to copy your App password, as it will only be shown once. If you miss it, you'll have to create a new one.
5- App-Password can be used in 3rd party software

To set up your email account, you can use the following ports and encryption methods:

- For outgoing emails, you can use ports 465 or 578 with SSL or TLS1.2 or higher encryption.

- For incoming emails, you can use ports 995 or 993 for POP3 or IMAP with TLS1.3 encryption, which is mostly used by modern providers.

* You can set TLS in zenon6.ini if you're using Zenon version 10.
