Delay in Receiving Certain Email Addresses

[revivingophelia]

As of yesterday I have been having problems in receiving a certain email address instantly (it is a vendors business email to my personal email).
It started yesterday. I received the email on my blackberry an hour after I received it in my inbox. Today it was two hours. I didn't have problems before then.

My email is Rogers Yahoo, and my service provider is Rogers, so I should receive emails right away. I sent two tests today, one from my hotmail account and the other from my university account and received them instantly.
Any ideas?

Thanks :)

Have you done a Battery pull or re-sent your service books? It is also possible the vendor may have issues with his Mail server.
