In which way may I create a cluseter of imap servers using FreeBSD ? any suggestions or hints ? The is the problem of the imap mailboxes. How can I syncronize them in real time on both machines ? I as thinking to cyrus imapd or dovecot as imap server, but anyway 20.000 mailboxes are really huge... And with cyrus imapd is impossible to achieve a real fail over system even using cyrus murder. Anyone knows which kind of solutions are used by yahoo for example ? thank you Rick
