Changes to iolfree e mail address settings on changing over to broadband?

Hi guys,
I have for a number of years had a dial up connection to access the internet and my e mails.I have a laptop with OS Windows Vista.I use Windows Mail for getting my mail.Esat BT is my ISP and I had set up an e mail A/C using the usual pop.iolfree.ie and mail.iolfree.ie settings.But I have now got a wireless broadband connection and I am unsure what way to go about putting new settings in situ.I am aware from my initial setting up of my iolfree A/C that this is a dial up type e mail A/C but I am hoping there is a means by which I can hold onto this A/C as it is pure hassle having to set up a new e mail address.I am well aware that I can check my mail on the IOL website but there is so much more one can do with Windows Mail.Hope one of you techno geniuses can help correct my settings.
Ta,
