"Configuration error found" in the new version

Hi there,

I would like to know how can i resolve some “configurations error”. I have about 9 contact form (in different languages) in my site and when I have updated the plugin it have appeared some mistakes like “2 configuration error found” in all the forms. For example in “From”-“[your-name] <[your-email]>” it puts “This email address does not belong to the same domain as the site.”.
Is it important? Could I ignore it? If not, how can I resolve? because I don’t understand very good the extra information.

Thank you very much,
Kind regards
