I'm with Telstra Bigpond and haven't had any issues with my @bigpond.com emails. It will have nothing to do with the OS, but everything to do with your email client. I use Outlook, what do you use?
Whatever client you are using, make sure that you have selected POP3 and:
- Incoming mail server: mail.bigpond.com
- Outgoing mail server: mail.bigpond.com
And ensure that your username (
name@bigpond.com) and password are correct.
