I agree. Sending mail to google (and also hotmail/outlook) has become very unreliable. E.g. when using @amsat.org or other forwarding services like @veron.nl or @vrza.nl (Dutch amateur radio societies) it will usually not work. I do not really want to use my ISP mail address, so it looks like I have to register my own domain to get this fixed. For now, I have set an autoreply (from the ISP mail address) encouraging people to use a different address and look in their spambox when they expect a reply. I hear that it is customary in the circles of gmail/hotmail/outlook users to send a Whatsapp message "I have sent you an e-mail"... Rob
