    Spam from Sub-Domains


      We have noticed an increase in spam from sub-domains.  The majority of the messages have been quarantined but I’m wondering if anyone else has noticed this anomaly.  It’s only been within the past month or so.  (For example:  xxxx@xxx.xxxxx.com)  Any particular reason spammers are utilizing sub-domains?  Thanks!
