Salutare,
Se da:
# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)
# uname -a
Linux mail 3.10.0-327.10.1.el7.x86_64 #1 SMP Tue Feb 16 17:03:50 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux
# rpm -qa|grep postfix
postfix-2.10.1-6.el7.x86_64
In main.cf am diverse restrictii obisnuite:
smtpd_client_restrictions = hash:/etc/postfix/access,
permit_mynetworks,
permit_sasl_authenticated,
reject_rbl_client zen.spamhaus.org,
reject_rbl_client bl.spamcop.net, [etc]
Ideea e ca pentru trimiterea de mailuri (prin portul de submission de
exemplu) sa nu faca verificarile de mai sus. Daca ma autentific sa fie
de ajuns sa accepte mailul si sa-l trimita, fara sa ma streseze de
exemplu ca ip-ul public de la care trimit este prin vreun blacklist. In
master.cf am facut asa:
submission inet n - n - - smtpd
-o syslog_name=postfix/submission
-o smtpd_etrn_restrictions=reject
-o smtpd_sasl_auth_enable=yes
-o receive_override_options=no_address_mappings
-o
smtpd_client_restrictions=permit_mynetworks,permit_sasl_authenticated,reject
-o
smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject
Si chiar vad procesul de postfix pentru submission pornit ca atare:
postfix 6717 0.0 0.1 106752 5780 ? S 01:20 0:00 \_
smtpd -n submission -t inet -u -o stress= -s 2 -o
syslog_name=postfix/submission -o smtpd_etrn_restrictions=reject -o
smtpd_sasl_auth_enable=yes -o
receive_override_options=no_address_mappings -o
smtpd_client_restrictions=permit_mynetworks,permit_sasl_authenticated,reject
-o
smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject
In schimb cand incerc sa trimit mail:
Jun 8 01:17:16 mail postfix/submission/smtpd[6260]: connect from
unknown[213.233.85.145]
Jun 8 01:17:16 mail postfix/submission/smtpd[6260]: NOQUEUE: reject:

[213.233.85.145] blocked using zen.spamhaus.org;
https://www.spamhaus.org/query/ip/213.233.85.145; proto=SMTP
Din teorie, ce scrie in master.cf face override la ce e in main.cf dar
la mine nu :-) Imi scapa ceva, dar nu stiu ce, asa ca daca aveti vreo
idee...
Mersi,
