Being able to store email more than 3 days (paid by storage used)
I would love to be able to store my email for long term and use it as an archive of those emails.
I would be ready to pay as per storage used.

For the love of all that is holy please do this. I can't tell you how many times now I've come back from a long weekend to have someone ask me for an inbound email that has been purged already. All I can do is look at the logs and cry.
