Those that use the Maildir format (Like for > example Postfix together with Courier-IMAP) does not need locking. What I'm building is not a mail server, but a storage, that could be used as a backend for a mail server, *for example*. In this sense, I don't even have a choice of what application to use. It can be a mail server, a database, a file server, or anything you can imagine. Sorry if this was not clear. -- cc
