Groundhog day....
As a SlySoft mail server admin, I was fighting more than 10 years against @att.net, @sbcglobal.net &Co. They all use the same internal email blacklist and we nĺever managed, to get off this blacklist. Nowadays as a RedFox mail admin, with a virgin mail server, I was quite relaxed. As I say: I was.
The complete neighbor network of our mail server is (was already before) blacklisted and I will not start over like this again.
I'm fed up now and started blacklisting back these att.net-blacklisters. So if you try to use a crappy email address on our contact form, you might get a message like this:

I find that bigpond.com and bigpond.net.au are also blacklisted and these were not on the original blacklist.No penalty's at all, even bonus dollars to retire a bit early, over 90% of the employees took the lump sum instead of the monthly annuity, taking the lump sum makes it easy to pass the money on to your kids, taking the monthly annuity when you die, the money stops coming in.
I have never had email problems with Slysoft before so why is Bigpond blaclisted
