I have multiple computers in my LAN and I have one dedicated server online. I would like each of these computers to connect via SMTP to the dedicated server and be able to send an email out to me.
Problem is I don't really know where to start, for previous work on my dedicated server I installed mail-stack-delivery (Postfix + Dovecot) This works fine for sending mail from the server. But I am unable to connect remotely to it.
What I want is to be able to connect to smtp.dedicatedserver.com, Port 25, Authenticate using some credentials, Send email with Sender/Name headers.
Thanks for any help you may provide.
