I had to send more than 500 emails / day. So i switched over to FastMail.

It works well, and i like having unlimited aliases that i can kill at any moment. But there's no way of disabling deleting messages. I wanted to be extra sure i wouldn't loose any messages and what support said was basically "just don't delete them and you are all set".

What is worse, they accept the default deleting of messages of some email clients. Gmail won't allow deleting from a POP email client, which is much saner in my view.
