Hello,
while reading through my logfiles I found this:
Oct 22 05:51:41 mail postfix/smtpd[10412]: warning: 60.52.87.69: hostname
tm.net.my verification failed: Name or service not known
Oct 22 05:51:41 mail postfix/smtpd[10412]: connect from unknown[60.52.87.69]
Oct 22 05:51:57 mail postfix/policyd-weight[20658]: weighted check:
NOT_IN_SBL_XBL_SPAMHAUS=-1.5 NOT_IN_SPAMCOP=-1.5 NOT_IN_BL_NJABL=-1.5
IX_MANITU=ERR CL_IP_NE_HELO=1.5 REV_IP_EQ_HELO=-1.25 (check from:
.verbe. - helo: .tm.net.) FROM_MATCHES_NOT_UNVR_HELO=1.6
<client=60.52.87.69> <helo=tm.net.my> <[EMAIL PROTECTED]>
<[EMAIL PROTECTED]>, rate: -2.65
For postfix it's a unknown host, but for policyd-weight it is not.
As far as I understand it, postfix does a forward lookup on the sender IP
and a reverse lookup on the result. If they match, everything is fine. If
not, hostname verification fails. Is that right?
policyd-weight seems to use just the reverse lookup on the IP for its
helo-checks. Wouldn't it be better to do it the postfix way?
Btw, I seem to get IX_MANITU=ERR very often. Is that "normal" for that zone?
Or does IX_MANITU=ERR mean NOT_IN_IX_MANITU (which I've never seen)?
Greetings,
Tom
