One of the things that seems to contribute are X- headers on inbound mail - each new X-header is a new named property.
Want to DoS someone? Send them emails with new X-headers - lots of different ones. Spam seems to accumulate them, for one. Just looking at your message from the list, I see 4 different X-headers: X-MS-Has-Attach: X-MS-TNEF-Correlator: x-ems-proccessed: jxfyzdhlyVyYF5VF4W3Asg== x-ems-stamp: sLcJ9ri/feAlRgbRlwdyOA== Kurt On Tue, Mar 17, 2009 at 13:20, McCready, Robert <rob.mccrea...@dplinc.com> wrote: > I’m not sure I understand this named property quota thing or how we reached > our limit….. > > > > (http://technet.microsoft.com/en-us/library/bb851492.aspx) > > > > but my question is, how big of a deal is it really?
