    Default reject emails from specific extension (namely <email>@<domain>.biz

    Hi Zimbra!!

    For some reason over the last few weeks we have been flooded with spam that all originates from the extension .Biz ... It is very annoying and has now drawn the ire of my CEO who manages to get several hundred a day. Even though it is unconventional, is it possible to block or reject all email that comes with the extension .biz for example jalsdjalsd@yahoo.biz or flights@gmail.biz? Most of the email domains are masqerading as common and popular email domains except for the 'biz' part.

    Any suggestions would be great

    PS: I am also open alternative methods that may work. I am not locked into any specific solution.

    Thanks

    So far from the logs, I can see some of the emails getting through. Is the following wildcard invalid

    *@*.biz

    I can try different combinations of wildcard if I am using them incorrect
