if done a mailbox archive test with postfix bcc, filtering with sieve to domain, user, date, mail-in , mail-out sort in subfolders i dont see urgent need for having each mail a file, as you may connect to the archive via imap client for restore one mail, mdbox to my knowledge is the best open compromise on filesystem mailbox formats for filesystems, but however maildir should work too if used in a well desigend setup, you might need scripting taring partitioning too, on the long run.

Dovecot also offers some archive solution, and a object store you might have a look on At the end this isnt a real postfix theme, its more about storage etc 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
