Are you using SPF at all?  If not, that is your problem.  We ran into that about 3 months ago and as soon as we created and implemented a SPF record, emails were delivered to Gmail.com.

is this working one, Failed or new setup.

If new one check SPF records 

if working one broken, then look at any user sending bulk email to gmail
