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[18.104.22.168]: 553 5.7.1 <email@example.com>: Sender address rejected: not logged in; from=<firstname.lastname@example.org> to=<email@example.com> 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!
