BB Bold :: Email Cannot Confirgure On 9900?

I have recently got in to a huge depression after my email couldn't be configured to my Bold.I have a domain email. When I try to set up my email on the device it says to contact the server but in the server the confirgurations are ok.On the same note my staff uses a blackberry Germini 8520i. He can run the same domain email on it.I was comparing this and found out that in his phone you can configure ports.I am really in need of a professional assistance.My Network Service provider Digicel technicial team cannot even get this confirgured as they say the server some how is blocking the email to confirgure. I tried to configure the same email on a windows 7.5 phone and it works perfectly in that phone
