,I use Zimbra Desktop 7.3.1. The product works excellent until I switch on a VPN service (Mcafee Safe Connect).
As soon as I switch on the service, Zimbra doesn't send letters.
Is this a problem with Zimbra or VPN service? What can resolve the issue? Whether VPNs reviewed here can help me?
Is there a VPN service recommended to use with Zimbra.
Thanks in advance!
