Hello,
I'm trying to setup the Gallery SMTP Configuration but I'm getting an error "Please enter a valid mail address". I'm using the following settings (that work with all of our other applications).

The error that I'm getting:

Even if I use my personal gmail account with the configuration below I get the same error as above, while I'm sure that it should work.

Does anyone have the slightest idea why i get this error?
Thanks in advance.
