Zimbra calendar invitations marked as virus

The updated AV signatures have now been picked up by all of our scanners which now resolves this issue.

We became aware of an issue with a third-party vendor yesterday causing Zimbra calendar invitations to be marked as a virus.

When notified the vendor quickly released updated AV signatures which resolve this problem but unfortunately it may take a few more hours before the update is seen by our scanners.

We shall close this ticket once the updates have been verified as live.
