Mail sync at filesystem level

Hello,

I'm currently building a mail infra using some decentralized filesystem for the storage.

As I'm wanting to get multiple "entry-points" (servers running dovecot + postfix + other mail-related stuff), all of them sharing the same storage (most probably xtreemfs), how will dovecot cope in this case?

As I see things:

server1 gets a mail for User1; it pushes it to the xtreemfs directory. server2 shares the same xtreemfs directory, thus it can access the same mail listing

User1 connects to server2: will he see the new mail? Will dovecot on server2 know about it?

Thanks!

Cheers,

C.
