I am seeing these in my maillog:
/var/log/maillog
Apr 29 15:17:15 inet08 postfix-p25/smtpd[18108]: NOQUEUE: reject: RCPT
from unknown[95.62.201.133]: 450 4.7.1
<static-133-201-62-95.ipcom.comunitel.net>: Helo command rejected:
Host not found; from=<> to=<owner-pac...@halisp.net> proto=SMTP
helo=<static-133-201-62-95.ipcom.comunitel.net>
And these in my dns query log:
/var/log/dnsquery.log
static-133-201-62-95.ipcom.comunitel.net
static-133-201-62-95.ipcom.comunitel.net.hamilton.harte-lyne.ca
static-133-201-62-95.ipcom.comunitel.net.harte-lyne.ca
static-133-201-62-95.ipcom.comunitel.net.mississauga.harte-lyne.ca
I would like to confirm that the last three oddball dns lookups are
somehow related to postfix's sender restrictions that I have
configured, reproduced herein:
smtpd_sender_restrictions =
permit_mynetworks,
check_sender_access hash:/etc/postfix/sender_access,
check_sender_mx_access hash:/etc/postfix/sender_mx_access,
check_sender_ns_access hash:/etc/postfix/sender_ns_access,
permit_sasl_authenticated,
reject_non_fqdn_sender,
reject_unknown_sender_domain,
permit
And if so then I would appreciate having the exact process explained
to me as well. I can guess at what is going on but I would prefer
certain knowledge if available.
/etc/resolv.conf
. . .
search harte-lyne.ca hamilton.harte-lyne.ca mississauga.harte-lyne.ca
And if not then can anyone suggest to what is happening? Have I
misconfigured something?
