that can be easily answered by just look at your inbound MX and the
amount of dul.dnsbl.sorbs.net and pbl.spamhaus.org hits

until the large botnet was killed a few months ago this was majority of
*all* mail traffic which wouldn't have been possible all the years by
your conclusion

-------------------------

current month blocked at postscreen level:

[root@mail-gw:~]$ cat maillog | grep spamhaus.org | grep -P
"127.0.0.(10|11)" | wc -l
1148

until this year it was 10 times more

-------------------------

delivered: 1371
blocked by contentfilter: 134
honeypot hits: 5206
