Email not pushing, corporate sync not fetching

[GSRacer]

I have 2 email accounts set up on my razr maxx (Gmail and Corporate email). The corporate account is set to fetch every 15 min, and the Gmail is set to push anytime a message is received. This worked great for the first month or so, but now it is very spotty. I'm noticing that that neither account is notifying me when new mail comes is, and I can only get the new messages to show up in the inbox by manually syncing. All my settings and passwords are correct. I have tried restarting etc., and nothing seems to help. I don't care all that much about gmail, but this is pretty crippling for me at work. I know I have heard others complain about this, but I have yet to see a solution. Any experience out there that might help?
