Hi, I hope someone can help. I have NBN and use a web based email account. Today two parties advised that their emails to me bounced back to them. One has NBN with TPG as his ISP and the other has IINET (which I understand is part of the TPG family) and uses ADSL+. Interestingly I received emails from others who have other ISP and I could email myself without a problem. Any suggestions? Please advise.
