Senders of email to me are receiving 550 #5.1.0 Address rejected

[Marcus1]

I have the exact same problem in which emails from other users Gmail accounts are not being received or they recieve a message about incomplete delivery.

Here is a report:

What was the solution to resolve this issue as I see there are several others in the community that have the same problem ?

Hi @Marcus1,

It is best to raise this directly to our postmaster via email (postrmaster@tpg.com.au) include your account details (Username/Customer ID and the affected e-mail address) also the error message.
