I do that with two Debian 10 servers - Postfix, PostfixAdmin, Dovecot,
MariaDB, Keepalived.
MariaDB in active/active mode, each node accesses the DB via localhost,
Dovecot with dsync replication, Keepalived for a virtual ip.
The MX record points to each node, DNS A/PTR records for the clients
pointing to the virtual ip.
you may have a look to
https://blog.sys4.de/loadbalancing-mit-keepalived-postfix-dovecot-de.html
its old but the loadbalancing part
maybe good enough as a pointer
I separated Roundcube from the mail server and have them running on two
separate VM's as i didn't want to expose the webserver on the mail
servers to the Internet.
There is also keepalived on the two webmail VM's for a virtual ip where
the users connect to.
Both Roundcube instances connect to the DB or SMTP/LDAP server via the
virtual ip there.
Working since almost two years without issues.

This is a new setup, running on RHEL 8 with the latest everything.
Has anyone out there set up a high availability pair of Dovecot servers
- with Roundcube and PostfixAdmin - successfully ?
