Insensitive works for me,.... Ohh,. A reminder,.... If you use lower(column) in comparisons,. You also need to use an index on lower(column) as appropriate... At least in postgresql you do.

So, we can support either case sensitive or case insensitive mailbox names. Currently, mailboxes are case sensitive when using PostgreSQL, and case insensitive when using MySQL. This might not be what we want. We would probably like to have case sensitivity to be consistent, whichever database backend we use. any opinions?
