I see I'm not alone in emails not being delivered to gmail recipients. I've got a 2 page document from roundcube and an 8 page document from google explaining why. As far as I can see if you send more that 5000 emails to gmail then you have to do some kind of registration. I suspect they are counting all out emails together as I'm nowhere close to 500 let alone 5000. Roundcube, please do the necessary registration please!
