Hi i have a opensuse based server. Running postfix as MTA.
i have configured to receipt a very low spam ammount.
Normally when i find a misconfigured server, i put them into whitelist. But i have a problem.
I need receive email of a server with this issues:
-not have a PTR record,
-Send from IP WITHOUT domain.
-Send from diferents IPs
-do not have a SPF records
-the MX records do not coincide with sendin IPs.
Code:
postfix/smtpd[25862]: connect from unknown[190.196.11.130]
postfix/smtpd[25862]: NOQUEUE: reject: RCPT from unknown[190.196.11.130]: 550 Client host rejected: cannot find your hostname, [190.196.11.130]; from=<onemail@bancoestado.cl> to=<othermail@otherdomain.com.ar> proto=ESMTP helo=<VS3K-EXCHT1.banco.bestado.cl>
postfix/smtpd[25862]: disconnect from unknown[190.196.11.130]
The curiosity is this issues is in a BANK, is incredible.
The only data that i can have is the helo field:
EXCHT1.banco.bestado.cl
How i can write a white rule for this server??
Aditional Questions:
RCPT from = smtpd_sender_restrictions ???
RCPT TO = smtpd_recipient_restrictions ????
How put into whitelist a dynamic email server?
