I am writing the next Wiki article about how to obtain the best score in the Qualys SSL Labs Security Test using the different Zimbra Collaboration Releases:
Is a Community Contribution Wiki, that you can edit if you have a Wiki account. If you have some expertise, or tweaks, or extra input, please add it to the Wiki, or let the feedback here. Could be great to have the best result in that test using Zimbra Collaboration, in their different Releases.
I'm waiting to hear from you.
