Hotmail is a real problem as they block anyone and everyone.
Had an issue that some of my rellies use hotmail yet all my and other ISP users emails were blocked to hotmail recipients.
After a lot of stuffing around, it transpired a hacker was using an account with my ISP, the biggest next to Telstra, so Hotmail just blocked everybody using my ISP. Not the first time it has happened.
Took a couple of months including complaints to Communication ombudsman to get rid of the block.
Can't see the logic with these so called free email services, not to mention the number of times hotmail has been hacked.
