Email delay issues

Hello. I did a search but did not come up with any answers. We have two storm2's on our account. Both are set up with the same email address. My wife gets emails almost instantly. My phone will be sometimes several hours later or even never. I have tried all of the usual stuff.....battery pulls, service books, checked every setting i can find. I don't see anything unusual. This is not a work phone. I know that there is a website online that you can register your phone with. Does anyone have the website address or a link? Or any other ideas?

Thanks,
Eric
