Hi Gabriele,
Thanks for bringing this to our attention! We're in the process of revising how we'll handle BETAs moving forward. With the new release process coming soon, there won't be "major" versions anymore. It looks like SmarterMail 17.x BETA category was accidentally hidden during our review. I've fixed it now.
