I currently have the Network Edition set up, and getting ready to deploy some 'beta' users. However, before I do: I need to make sure archiving is working.

Archiving is working for current users in zimbra using the amavisArchiveQuarantineTo attribute. When I run a pst import I can see emails being directly injected to the mailstore using LMTP, however they are NOT being injected into the archive server. Monitoring the mta, I see no activity. Is there some attribute that I have populated incorrectly??
