Hi there,
I know it's not the right list to write to, but I'll still try a shot.
I'm running sendmail in my FreeBSD box and wish to block mails comming
from domains with no ptr configs.
Am I missing something?
My sendmail-rx.mc is like this
FEATURE(`access_db',`hash -T<TMPF> -o /etc/mail/access.db')dnl
FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable.db')dnl
FEATURE(redirect)dnl
define(`confUSERDB_SPEC', `/etc/mail/userdb.db')dnl
define(`ALIAS_FILE', `/etc/mail/aliases')dnl
FEATURE(`blacklist_recipients')dnl
EXPOSED_USER(`root')dnl
FEATURE(`use_cw_file')dnl
FEATURE(`use_ct_file')dnl
FEATURE(`use_client_ptr')dnl
FEATURE(`delay_checks')dnl
dnl #
dnl # configuracoes de lista de spammers
dnl #
FEATURE(`dnsbl', `dul.dnsbl.sorbs.net', `"550 Mail from "
$`'&{client_addr} " refused - see
http://www.dul.dnsbl.sorbs.net/"')
FEATURE(`dnsbl', `sbl.spamhaus.org', `"550 Mail from "
$`'&{client_addr} " refused - see
http://www.spamhaus.org/sbl/"')
FEATURE(`dnsbl', `list.dsbl.org', `"550 Mail from "
$`'&{client_addr}
" refused - see http://dsbl.org/"')
FEATURE(`dnsbl', `bl.spamcop.net', `"450 Mail from "
$`'&{client_addr}
" refused - see http://spamcop.net/bl.shtml"')

For purposes of making the subject less true, setting up greylisting
with an optional tarpit for known baddies can be very effective. See
Dan Langille's recent Onlamp article[1] or for that matter my tutorial[2]
for how this is done using PF and spamd - this way it doesn't matter much
which MTA(s) you use.
