I'm trying to figure out why some cannot send email.
In my postfix main.cf I have :
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated
defer_unauth_destination
smtpd_helo_required = yes
smtpd_helo_restrictions =
permit_mynetworks
permit_sasl_authenticated
check_helo_access hash:/etc/postfix/helo_access
reject_invalid_helo_hostname
reject_non_fqdn_helo_hostname
reject_unknown_helo_hostname
smtpd_sender_restrictions =
permit_mynetworks
permit_sasl_authenticated
reject_unknown_sender_domain
reject_unknown_client_hostname
reject_unknown_reverse_client_hostname
Some mail gets rejected with :
Aug 18 14:01:26 gw1 postfix/smtpd[171903]: NOQUEUE: reject: RCPT from
unknown[95.97.58.162]: 450 4.7.25 Client host rejected: cannot find your
hostname, [95.97.58.162]; from=<xxxxxxx at mijnders-transport.nl>
to=<xxxxxxxx at xxxx.com> proto=ESMTP helo=<mijnders-transport.nl>
But then when I do :
host 95.97.58.162
162.58.97.95.in-addr.arpa domain name pointer smtp.mijnders-transport.nl.
I already added the domain to helo_access, where am I going wrong?
