Yes. Smartermail is good but can anybody advise me how to backup emails from inbox? Memory will get full once you reach the capacity and once full, can we still receive emails?

Hi Juhair!

 

I'm happy to hear that you purchased a license. Whether you need the Cyren add-ons for antispam and antivirus really depends on your business needs. Some companies are fine with the built in tools and others really like the additional security of the paid add-ons.

 

If you're not sure if you need them, what you can do is start trials of the add-ons. This will allow you to test out the products for 30 days before deciding whether to purchase them. If you'd like a comparison of the two, you can go a bit with just the built in functionality and then enable the add-ons to see which you like more. Listed below are some resources that should assist you with setting up the antispam configuration and starting trials of the add-ons.

I hope this helps!
