Hello,
I currently have one machine running postfix SMTP server as MTA along
with dovecot IMAP server for email. Although it only supports a handful
of users, email service is important to us all; so I'm looking to make
this a more fault-tolerant / highly-available system.
To that end, I'm planning on configuring postfix to use
deliver/dovecot-lda as my MDA (using procmail at the moment), spinning
up another machine with postfix/dovecot and setting up master/master
replication using dsync/doveadm-sync. My reading on the subject
suggests that this should (given appropriate MX & SRV dns records) make
traffic balanced across both nodes, and the system should be resilient
if one of the nodes should fail without the need for much/any human
intervention.
In order to replace the functionality that procmail currently provides
as MDA, I was thinking to use Sieve. Fortunately, it seems the
Pigeonhole project provides almost everything I need on the server side
to make this work. The one potential gap I have identified is the
syncing of the sieve scripts between the two machines. Has any one
dealt with this and come up with a good solution? Does dsync already
handle this and I just haven't figured it out?
Let me know if my question is best directed elsewhere.
Thanks in advance for any help,
--Joe
