EmailAddress: Illegal value for EmailAddress

Hi,

I got this error whenever I try to put my personal
email address carlos@amiga.com.pl (which seems to
be valid) in user’s email field. Solution?

Have you crashed your Windows today?

When modifying a user I’m receiving the following error. EmailAddress:
Illegal value for EmailAddress. Has anyone else seen this?

Thanks.
