I have this message
"Invitation failed - bad email"
when inviting people to my site. It happens only when their email is like email@example.com
Maybe you have some mail address validation that fails for such short domain name? I can assure you that wp.pl is good mailserver domain name...
We will investigate this issue.
In the meanwhile, I will fix these emails in your site manually.

"Invitation failed - bad email" .....
I have the same problem with firstname.lastname@example.org
Thanks for reporting this!
I've manually fixed this for your site.
We will investigate why this has happened.

... also can't invite anyone with email@example.com e-mail address....
Maybe it's globally problem.
I fixed the invitation for Anna in your site members list.
I've also let the developers know that @wp.pl addresses are causing problems.
