I currently have Postfix Dovecot MySQL on Centos 6, looking at migrating to new server
new server is CentOS 7.3, but, the Centos repo version is
dovecot x86_64 1:2.2.10-7.el7
what is the best way to install current release Dovecot on a new server ?
GhettoForge has dovecot22 packages as well which provide the latest stable version of Dovecot for CentOS 6 and 7.
Or consider compiling it yourself from source. It may be more work, but you get complete control over your versioning, your package dependencies, etc. If a bug that affects you gets fixed on a bleeding edge version (or is only available as a patch), you can fix it right away rather than waiting for the package maintainer to catch up to it.
