I need to add a new account to Outlook. This account belongs to a postfixmailserver. For POP settings, I set port number 110 for incoming and port number 25 for outgoing mail. As the server doesn't use an encrypted connection and the ports that are available for POP and SMTP are 110 and 25, in the POP setting, set these ports as incoming and outgoing mail. Trying to connect failed with this error:
We couldn't connect to the outgoing SMTP server; please check the outgoing SMTP server setting.
