Maildir is a standard specification http://wiki.dovecot.org/MailboxFormat/Maildir http://wiki.dovecot.org/MailboxFormat/ there is no easy answer what might be better to use at your side , this depends on your setup ( how many mailboxes, how many mails , how big are mailboxes etc , storagekind etc, traffic , how many pop3 vs imap logins ) your dovecot version is very old , you should upgrade or migrate in any case Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
