I have a weird issue on an 8.1 VM Pro server(Windows). I go to configure the SMTP sender, click OK, and the entry disappears. If I do not check the "Server requires auth" box then the settings stay through a save. As soon as I check the box and hit OK, the entry disappears even if I do not save and make live before going back into the settings. I was going to try and run a repair on the software after hours and see if that does the trick. Has anyone seen this before? Any suggestions to fix it without repairing the software?
