SSHGuard works fairly well with Postfix; however, it is virtually useless with Dovecot. [..] I have submitted documentation and requests to SSHGuard, but they have never acted upon them [..]
Just to add another alternative while we're discussing the subject, I've got a soft spot for CSF as a replacement for fail2ban, and it has a lot of additional features as well.
In case it matters to anyone reading this thread:
fail2ban and SSHGuard are free software (free as in freedom). GPL2+ and ISC respectively.
CSF seems to be non-free: https://download.configserver.com/csf/license.txt
