Recent releases log this mistake as a warning:
postfix/postmap[2328]: warning: cidr map /tmp/dict, line 1:
non-null host address bits in "255.255.255.255/24", perhaps you
should use "255.255.255.0/24" instead: skipping this rule
postfix/smtpd[2355]: warning: mynetworks: non-null host address
bits in "255.255.255.255/24", perhaps you should use
"255.255.255.0/24" instead
postfix/smtpd[2355]: NOQUEUE: reject: RCPT from
tail.porcupine.org[168.100.189.3]: 451 4.3.0 <u...@example.com>:
Temporary lookup failure; from=<> to=<wietse> proto=SMTP
The reason not to accept mail with this mistake in myetworks is
that it caused somone's system to become an open relay.
