I'm on the non classic interface (the standard gui) I tried to send an email to
The email address is valid and I'm able to send to it via another client or the older interface, but with the standard gui, I get the message
We cannot find a match for this email address:
Please use an email address that looks like
firstname.lastname@example.org a nickname or a distribution list name from your Yahoo! contacts.
Does anybody know how I can send the email to that email address with the standard Yahoo! mail GUI, and without getting that error message?
