BB Software :: Email Settings For Email With No Static IP Address?

I have been a Blackberry fan for years and have setup countless Blackberry's for friends. I recently changed jobs and therefore, had to change my email settings, to receive work emails on my Blackberry Torch. I emailed our hosting company and asked for the settings to setup my phone, I received this response: (have blanked out my details for security reasons)To setup the email account on your BlackBerry device you will need the following information Email address: ********@******.co.zausername: ********Password: ********Incoming mail server: The incoming mail server is tricky as your organisation doesn't have a static IP address. For now try IP Address: **.***.***.***I have tried these settings as well as the settings in my Outlook account settings folder (the incoming server on my Outlook is a local IP Address, to the server in our office)None of which have worked. I have contacted both our hosting company and Vodacom (my BB service provider) neither are able to assist me? Even my husband (who is an IT specialist has tried, with no luck) I then tried to use the BIS html option to find my settings, but for some reason Vodacom does not allow this, I received this error message when trying to logon/register: Your account is not accessible via HTML browser.
