For those interested I've located the UOL link for their UOL Email Backup (Dropsuite).

https://email.uol.com.br/backup-de-email/#rmcl

Pricing - $9.99/m Brazilian Real 5gb storage (with other options available).

Equates to approx $3.40/m AU.

Dropsuite must be charging something less than $0.92/m as this contract appears to be the one that has driven the ARPU down.

So UOL have scored a pretty good deal here but I guess some customer friendly deals like this are needed at this stage to build scale quickly. Plus they clearly have produced the goods with bulk sign ons, maybe with more to come.
