> Do "typical" installations use altnamespace or the hierarchical name space?
One point I didn't see on the list about this so far in regards to "typical" installations and unix hierarchy separator feature is that without it there is now way to have a "." in the mailbox name which is important in at least two "typical" situations. 1) firstname.lastname as the mailboxname/userid or any situation with "." as part of the ID. and 2) "[EMAIL PROTECTED]" as the mailboxname/userid The first is common in some large organizations. The second is for all Cyrus installs of versions 2.0.x and 2.1.x that want to do single IP virtualhosting without implementing some sort of rewrite or lookup schema. Version 2.2 will no longer need the unixhierarchy option to support this. I'd consider both of these a common enough mail installation to make the unixhierarchy separator worth mentioning. -- Michael --
