• Should we have it as a per mailbox through ANNOTATEMORE like
several others? (Dave)
• Should we have it as a per NAMESPACE? (Pete McLean)
One other possibility that was not mentioned was using the QUOTA extension.
That does have an extensibility mechanism that would allow a MAXAPPEND
property.
That said I personally would prefer an ANNOTATEMORE approach as I do see
this as being useful for both 'static' server limits as well as 'dynamic'
per-mailbox quota limits. Different server implementations/deployments will
likely have one or other of those limits so we need to provide a way to
handle both.
Adding a /limits/ entry hierarchy for ANNOTATEMORE would be easy and would
allow for specifying other limits if they are needed (e.g. MAXKEYWORDS,
MAXSEARCHTERMS etc).
