Re: [Dovecot] Mailboxes separated from IMAP server

21 Oct 2013


      I know how HA n LB works, is just that is not what I'm looking for for
example if you have and imap server that stores the mailboxes in a LUNs of
a SAN, that only store the emails received for the postfix servers,
transfered by LMTP way, how you can configure another IMAP server that use
POP and IMAP protocols without access the SAN just communicating with the
other Dovecot server...

no i am not kidding you
what i linked is how in professional environments typically things
are done - virtually nobody would talk from one IMAP server to
another one to deliver mails to the client
with clustedred and replicated filesystems you have all servers
accesing the same mail storage and your DNS-record has all of
the servers listed
http://en.wikipedia.org/wiki/Round-robin_DNS
so before you assume someone is kidding you google how load balancing
is done in large environments, read the links others provide and if
you are not on a that large environment one server would be enough
...
Are you kidding me? Is not how or where to store the mailboxes... is how
to connect an imap server to another IMAP
server that have mailboxes!
