I have many log entries where there are "helo=[1.2.3.4]" entries with
no domain name. It has an IP address only. Each of these occasions
are unwanted spam messages.
Can some one specify a policy restriction that will block these messages.
An example from the log is:
Dec 22 16:00:52 hera5 policyd-spf[9883]: None; identity=mailfrom;
client-ip=75.211.27.210; helo=[63.205.88.41];
envelope-from=dtrue-nore...@example.com; receiver=u...@example.com
Thanks in advance for any suggestions on this.

You can use reject_non_fqdn_helo_hostname in the smtpd_helo_restrictions
parameter. For example:
smtpd_helo_restrictions =
permit_mynetworks
reject_non_fqdn_helo_hostname
reject_unknown_helo_hostname
permit
