I've also passed this onto our Network Team to identify if this is a known issue and if they have any further information for us.
As soon as we hear back, we'll be able to let you all know here.
Hey all, our Network Team have got back to us and mentioned they're aware of this issue and looking into it.
We have this being investigated under fault ref: #23304755
We don't have any further info at this stage, however, we'll keep everyone in the loop once we find out more. Apologies for the inconvenience caused.
I've also been affected in the same way. I have logged into the senderscore site and it thinks I have been sending up to 50,000 emails some days. Not true, I'd average 2 or 3 with nothing slightly offensive or questionable. My senderscore is somehow 6 out of 100. Telstra uses the senderscore to block unsavoury companies using the system. The company that compiles the score is called Validty. Like most IT companies they live behind a barrier the average user can't get past - unreachable and unanswerable to anybody.
Optus could really help by providing some information here. Is the blockage being done on an individual basis, does it affect all Optus customers, just some on a particular server or those bound to a particular IP address? Would moving affected customers to a new IP address fix the problem? Is Optus sorting this on behalf of its customers (it would have the data to clear their names) or do we customers have to sort this ourselves? But don't hold your breath.
Hey @nigedes - Our team are still assessing this and are awaiting for communication from the host about this issue. I'm afraid no further updates besides this are available at this stage.
