I continue to receive spam on my current Optus email address. Can I disable this email address so that I cease getting spam, and create a new Optus email address?
If you are on Optus broadband, you can't delete your primary email, but you can create secondary ones you could use.
Go to the User management option.
I use this method to route my Optusnet email through Gmail, as Gmail has much more effective spam blocking.
In this way I never need to look at my actual Optus email account (not in Outlook POP3, mobile phone IMAP4 or on Webmail) and it can collect all the spam that Optus wants to let it have, however all I see in my actual email (no matter where I view it) is a clean Inbox thanks to how well Gmail filters out the spam, which works a treat, and there was no need to change my actual Optusnet email address!
