[SSHGuard-users] Blocking IP with Postifx

[Gerard S. <car...@ou...>]

Normally, sshguard works perfectly with Postfix. It detects new IPs and
blocks them as appropriate. However, there is one that it never blocks.
This is the Postfix log entry (one of many) that relate to this IP.

Jun 26 06:37:20 scorpio postfix/smtpd[98953]: warning: hostname
50-246-67-11-static.hfc.comcastbusiness.net does not resolve to address
50.246.67.11: hostname nor servname provided, or not known

Jun 26 06:37:20 scorpio postfix/smtpd[98953]: connect from
unknown[50.246.67.11]

Jun 26 06:37:21 scorpio postfix/smtpd[98953]: disconnect from
unknown[50.246.67.11] ehlo=1 quit=1 commands=2

Why is this particular IP not being added to the database and then
blocked.

I am running FreeBSD-11 / amd64 with Postfix: version 3.2-20160612 and
sshguard 1.6.4

Is there a way to manually add the IP to the sshguard database?

Thank you. :)
