Can send and receive mails locally, but only receive remotely.
Hello, I've setup a virtual server which works fine, now I've been trying for the last couple of hours to figure out why my emails wont send when I try to use mail clients like thunderbird and outlook, when they can receive just fine. Outlook says it can't cannot to the outgoing(SMTP) e-mail server. And Thunderbird just times out.
The server is a remote dedicated pc runing Ubuntu 16.04 LTS and no ports should be blocked.
This is what my mail.log shows when attempting setting up the account in outlook
