Thanks for your reply IgorG.
A other question i want to buy MagicSpam on the Plesk website only the thing is it's unable to buy:
We are not able to process the requested order. The product license you are requesting an update to is managed by an Parallels Partner or Software Reseller who supports the inclusion of features to their licenses. As such, they are your first point of contact for license updates.
I already contact the reseller but the don't offer MagicSpam.
Greetings,
Marco
