The best to do: ask them. They will have a FAQ-page and a technical helpdesk that knows about their services. I don't think you'll find anybody here who can help you.
For a long time now I have been using Gmail to fetch the mail from my school's email account because it was a real pain having to check both sites. I have about 6 email accounts all together but my most used are my school's and G-Mail.
Now recently "My Internet" (provider for Australian Educational Internet) has revamped it's webmail and is now called editure. My internet address is still the same, folders and old e-mails are still there too but what has really stuffeed me up is that I can not seem to access my email using POP. I think the webmail service they are using is based on squirrel mail. I hope this helps and you can help me.
I have left some server information that I "WAS" using below.
POP Server: mail.olrwyoming.dbb.catholic.edu.au
P.S. in Editure, When you delete somthing it goes to trash then you have to PURGE it to delete it out of that. We used to have to do that for our old AOL Account, doesn't it have to do with SMTP or somthing
