org.apache.james.mailrepository.MBoxMailRepository

MBoxMailRepository
public class MBoxMailRepository extends AbstractLogEnabled implements MailRepository,Serviceable,Configurable,Initializable(Code)
Implementation of a MailRepository using UNIX mbox files.

Requires a configuration element in the .conf.xml file of the form:
<repository destinationURL="mbox://<directory>"
type="MAIL"
</directory> is where the individual mbox files are read from/written to
Type can ONLY be MAIL (SPOOL is NOT supported)

Requires a logger called MailRepository.

Implementation notes:

This class keeps an internal store of the mbox file When the internal mbox file is updated (added/deleted) then the file will be re-read from disk and then written back. This is a bit inefficent but means that the file on disk should be correct.

The mbox store is mainly meant to be used as a one-way street. Storing new emails is very fast (append to file) whereas reading them (via POP3) is slower (read from disk and parse). Therefore this implementation is best suited to people who wish to use the mbox format for taking data out of James and into something else (IMAP server or mail list displayer)
