Earlier it was working for me but I could not attach files. Depending on a single provider is a recipe for disaster and I expected their infrastructure to be more robust. Mail is critical infrastructure. At least the messages aren't bouncing or so I hope.

I guess using aliases indiscriminately was a bad idea after all as it increase the cost of moving to another provider. Not that there's any reasonably alternative on this aspect but they being an Aussie company and Australia government pushing hard to become a police state is making me unhappy.
