Reports are coming in that if you send a Gmail invite to someone with a YahooMail or HotMail account, your invite email gets caught in their spam filter and disappears into the cyberether. Your recipient may never see it.

First edit for clarity: the news reports don't indicate that all invites are disappearing, just some of them.
Second edit for clarity: As an employee of Google, let me be clear that I have no idea precisely what is causing the problem. Personally it sounds like a spam trap problem, and I also (personally) find it suspicious. I haven't been told anything official from the Gmail team or Google in general. I'm pretty much just passing on a news report to y'all.
