I have one of my developers using a program called monit (don't know a lot about it). Its used to send alerts about various systems in linux (we use ubuntu).
some of these servers using monit and ubuntu are on servers off of our main network. what i've done is made a special receive connector with a different port number other than 25 and only allow IP's that we trust (using our firewall). I've enabled basic authentication as well as only allow basic authentication after starting TLS.
My developer tells me that im only presenting auth login and not auth plain. monit doesnt support auth login. it only supports auth plain. since i dont know the program i can't do any testing to see what options come up after initiating a starttls.
I though if i selected basic authentication it would allow both auth plain and auth login?
