Owncloud 10 does not share to email addresses ending in .us or other

Hello - I have tried in many different ways now, but I cannot get the sharing function in OC 10 to share to an email address ending in .us

It just disappears from the box, but if you type one ending in .com or .org it stays in there just fine and sends fine

This is on the right side in the interface, and is the public sharing option where you enter an outside email address (does not have owncloud account). Again, normal email addresses ending in .com or .org work fine, nothing wrong there. Any other email domain not ending in these does not stay in there and will not send to them

this may be a bug

Hey,

i think about the same and would also report a bug for this.
