Karanbir Singh pointed me to a problem ( Gmail might say that it is intentional) that Gmail has with it's email system. Whenever we sent out email to non-existant Gmail email accounts from non Gmail addresses or even in Gmail address, we do not get any “Permanent errors” or “fatal error” messages back to the senders address which is normally the case. As per Karan, they store the emails.”What makes it quite interesting is that someone signed on as {username}@Gmail.com and found over a 100 e-mails waiting for him on his first login, some from as long as 2 months back. Apparently someone had been mistakenly sending emails to this {username} and the emails seem to have been stored up” . I have checked this myself using my Hotmail and other accounts and send email to some non existant gmail account 4 days back and I have'nt received anything so far back in error messages. This to me is a sign of warning to both senders to Gmail addresses and receivers of Gmail email. As for senders, you better make sure that you type the correct Gmail address otherwise you won't know whether the receiver really got the message and for receivers make sure you really stress hard to your senders to put the address right the first time.
Has anybody else want to add anything to this?
