I use SSHGuard on well ssh (doh!), but supposedly you can use it for postfix and dovecot also. I can tell you it is well supported. I am on Centos 7 using firewalld.
SSHGuard works fairly well with Postfix; however, it is virtually useless with Dovecot. It never picks up on "auth fail" and a few others. I have submitted documentation and requests to SSHGuard, but they have never acted upon them, other than to say that they will look into it.
