I'm unable to create an email account in email client. It gives an authentication error. when I'm sending an email from telnet then email send properly.

Can you please guide me?

Thanks

Solution

You should just need to add this line to your main.cf queue_directory = /var/spool/postfix and then restart postfix.

Conversely, it might be worth attempting to put the entire path to the private/auth file, if the first method does not work.
