Cant save nodeworx settings


I am trying to enable ruby on a server under the nodeworx settings but I cannot get past the settings for Mail Options. It will not accept blank or anything that I put into “Default Sender:” What needs to go there. I have put email address to hostname but nothing gives.

Current version 4.7.0-339


All that needs to go into default sender is an e-mail address that the server’s warning messages appear to have come from. For example, info@server.tld .
