my meaning crypted mailstore makes sense in a mail archive, in germany you have to have a mail archive for some kind of company emails all these solutions have some crypted mailstore , and some more features for data security, but thats a big theme, to big for here crypt storage isnt "the saveness" per default, someone hacking the system and get root may hack your crypt storage too etc, also to big theme for here in working mailservers end to end encryption is/should be state of the art with smime/gpg 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
