I never got such a response. There was a time when a message wouldn't go to a new recipient if it contained any web address - but I'd rather ascribe that to the recipient's own spam filter. But the message would get sent, it just never made a blip on any screen.

I'll check with my daughters to see if they have seen anything like this.
