Hi, I don't think Gluster is the correct tool for the job: sync 
replication and file lookups will suffer tremendously due to the high 
latency WAN links, grinding all to an halt. Geo-replication should be 
out of question, because it is a read-only copy from source to dest 
(unless things changed recently).

For such a project, I would simply configure the SMTP server do to 
protocol-specific replication and use a low-TTL DNS name to publish the 
IMAP/Web frontends.

Regards.
