Zimbra Thortle Blocking

This solves the problem if your Zimbra is blocked by the throttle feature.

To check which IPs are suspended, you can look in the mailbox.log file for entries showing the suspended IPs.

Solution:

zmprov mcf +zimbraHttpThrottleSafeIPs (your_IP)
zmprov ms `zmhostname` +zimbraHttpThrottleSafeIPs (your_IP)
zmmailboxdctl restart
