COMMENT:
----------------------------------------------------------------------

Thanks for your work on this extension, it seems useful, I just have a
few comments that can be left to the editors and AD to handle if I
disappear for maternity leave.  

I think the security considerations section could be a bit more clear on
the actual risks with this extension.  I think the flow of the section
can be improved to make these risks a bit more clear.

First, this extension lets you find out the limit for either the server
or individual mailboxes, so shouldn't the first part of the description
focus on a possible DoS filling up those resources?

I'm not sure why there is a focus on "without this extension".

Then, it's a common security programming practice to enforce size
limitations in code.  Why is there a focus on an attacker sending append
content that exceeds the allowable size rather than just saying that such
append content should be rejected?
