I can only second that. Official FreeIPA plugins for Postfix and Dovecot would be immensely helpful.
Someone made a plugin that adds mailAlternateAdress to the scheme and ui, which is somewhat related to this issue: https://github.com/pdf/freeipa-user-mailalternateaddress
To be clear, my proposal was for someone outside the IPA team to do the packaging and we would provide assistance.
