Dear
EMail Sender.
We
will launch a series of security checks on our e-mail servers on October 1,
2020, in order to securely exchange e-mail with subcontractors in our ecosystem
and companies and institutions with which we are commercially related.
In
this context, it is recommended that the companies and institutions we work
with should implement their PTR, SPF, DKIM domain name registrations and DMARC
policies on their domain name servers until October 1, 2020, in order to ensure
proper e-mail communications with our company.
E-mail
communication with institutions that do not publish the above-mentioned records
in DNS records will be marked as suspicious (SPAM) e-mails on Aselsan servers.
After
automatic controls, the mail you have sent had been flagged as unconformable
with the DKIM policies that will be implemented.
Sincerely,
healthy days.
▷ 질문내용 : DNS 서버에서 구성하는 걸로 압니다.
다만 해당 메일서버가 DKIM, DMARC를 지원하는지요
