I currently run a HA postfix/dovecot setup that is failover behind a
HAproxy. The two legs are a dovecot 2 on macOS (MacPorts) and a dovecot
2 on Ubuntu (PVE+Ubuntu+Docker), making the system somewhat antifragile.
HA is realised via dovecot's own syncing (which is not longer available
in dovecot 3). This works OK. (In addition: there is rspamd as an
important part of the setup, e.g. for DMARC). There are multiple virtual
domains.
Given that I have lost APNS (Apple Push Notification) as Apple has
retired support for former Mac OS X Server users, there is not longer a
reason to keep the macOS version running (apart from that antifragility
thing, but that was more an added bonus). I am looking at moving to a
different setup where the entire mail setup may move to a full Linux
foundation.
I am starting to look at future options (there is still time to actually
create the setup somewhere the coming year or so.
If I want to be future-dovecot proof, I need to move to HA for storage
as dovecot syncing is deprecated. I wonder what my best way forward its,
based on a 2 physical machine, PVE+Ubuntu+Docker setup. Build a HA NFSv4
cluster? Use Ceph? ZFS?
Dovecot syncing is not deprecated, replicator is. You can run a PRI/BU setup with doveadm sync in cron.
