dns loadbalancing does not play very well, so you want no traditional mx backup mailserver instead you want some HA Setup with all mail related stuff ( smtp/pop3/imap/webmail ), using drbd/nfs and loadbalancer/directors are the way you have to go, postfix isnt the harder part for that, so better ask and serach for HA setup with dovecot first, i.e on dovecot list 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: Joerg Heidrich
