Hi,
currently it is not possible to define a notification-sender like 'My Name <my.name@domain.com>' because GFormDisplay::send_email() sends the whole string to GFCommon::is_valid_email().
GFCommon::is_valid_email() validates for a correct mail-address syntax only, not recognizing the name/string before. Therefore the e-mail is invalid and the blog-wide default from-adress is taken.
Please make GFCommon::is_valid_email() or GFormDisplay::send_email() recognize the "Name <email>" syntax.
Thanks in advance.
Regards,
