Unaccepted meeting invites going to calendar?

[fimchick]

Hi,

I have a user who's exclusively on Zimbra Webmail and on his Blackberry.

He receives spam messages, some of which are calendar invites. Zimbra automatically puts these invites on his Zimbra and Blackberry Calendar even though he did not accept them.

I know there's a way to turn off "automatic meeting processing" in Outlook, but how do I do that for Webmail?

Thanks!
