Exchange 2003 5.2.1 error bounces emails seemingly at random
SBS 2003 Exchange with SP2 no other rollups after that.
Server is upto date except some .net crap that won't install.
Email sent from outside LAN will sometimes bounce back to the sender with 5.2.1 error.
We have removed all limits on email sizes
It's not consistant at all, some will bounce some won't, we can't find a trigger that causes a message to bounce. Sometimes a message that's 17K will bounce from the server with a return to sender of 5.2.1
There does not appear to be anything touching the traffic like Anti Spam software or odd firewall software on the server.
Just plain old Anti Virus installed.
A telnet email session (25) with the server always results in a sucessfull email. With no 5.2.1 ever returned in my manual session with the server.
This has been going on for a few weeks, and I can not figure this out!
I have done extensive searching on this site and others.
Because it's across multiple users, I ruled out a currupt single user box.
Below is a transcript of a returned to sender message.

Yep found LOTS of 9667
Cranked up the registry for NonMAPI Named Props Quota and Added Named Props Quota and set it to the same value.
Then dismounted and remounted the store.
So now we wait till I hear back from users :)
