I have LMS 3.0 installed and running fine but I was not getting emails when jobs were completed. I tried deleting/re-entering the SMTP server info from the "server settings" portal. Now I get an error every time I try to put in "localhost" (which is what it was set to before). It says "Invalid IP address or server name for mail server. Please enter a valid SMTP server name or leave the 'SMTP Server' field blank.". I need to get this fixed asap, anyone else have this problem? I have no idea where to look (log, etc..) to troubleshoot this.
