I have a user who installed vpn/ip masking software for web browsing. It appears to also affect thunderbird. He can’t send email. I’m running Ubuntu 16, postfix, and dovecot. I’d prefer to keep postfix locked down so it can’t be used by random people as a relay. How can I allow the user to send email when his ip address is changing randomly?
No one else is affected.
