Ok, I know that's not a very descriptive title, but that's where I'm stuck. I successfully installed (and tested the sending/login parts before removing my installer directory), but unfortunately, when I go to the URL for RoundCube, I'm presented with Username, Password, and Server text fields. Well, that's where I'm lost. What do I use for the server field, or how do I remove it to login? See attached screenshot to see what I mean. Thanks in advance!
