Hi! Most of the time I receive mails without problems, but today I found out that Postfix rejects incoming mail that is sent by me from an external mail server:
Nov 29 14:22:20 taitava postfix/smtpd: NOQUEUE: reject: RCPT from unknown[184.108.40.206]: 553 5.7.1 <firstname.lastname@example.org>: Sender address rejected: not logged in; from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<mail.rst.dk>
This mail is sent from a Windows server by an invoicing application. I should be able to send mail from external mail servers that indicate my email address as both a sender and a recipient. How can I setup postfix to accept mails sent this way? Will it do any harm?
Thank you for your support!
