Hey there prospective helper person!
My question just got many times simpler.
I have this all working now from the local box, (that being the computer that Ubuntu is installed on)
I can email gmail or yahoo address and such.
However, when I telnet into the IP address of that box to test sending an email from a different computer via telnet IPaddress 25, my
rcpt to: email@example.com
still gets rejected with a
554 5.7.1 Relay Access Denied
So really... hopefully there is only one thing left to solve.
As before, any help would be maximum appreciative.
