Here is what I use:
# Filters
filter dkimsign proc-exec "filter-dkimsign -d mydomain -s 20210622 -k
/etc/mail/dkim/private.rsa.key" user _dkimsign group _dkimsign
filter "rdns" phase connect match !rdns disconnect "550 DNS error"
filter "fcrdns" phase connect match !fcrdns disconnect "550 DNS error"
filter check_dyndns phase connect match rdns regex { '.*\.dyn\..*',
'.*\.dsl\..*' } \ disconnect "550 no residential connections"
listen on socket filter "dkimsign"
listen on localhost filter "dkimsign"
listen on eth0 port 25 tls pki mydomain filter { "dkimsign", "rdns",
"fcrdns", "check_dyndns" }
Hope that helps.
