Why is Gmail blocking emails from hotmail?
I have a Google mail account and I use that for business but the problem is that I am not able to send emails to them from my hotmail. Hotmail says they are undeliverable with the diagnostic code "smtp; 550 Unrouteable address". All other emails appear to be coming in fine. The hotmail ones are not even appearing in junk mail. Is there a problem with settings or what please suggest!
