i having the following error in the mail.log log file.
Aug 30 11:40:53g postfix/smtp: 3EE79836A7: firstname.lastname@example.org, relay=mail.example.com[18.104.22.168]:25, delay=79, delays=76/0.14/1.9/0.43, dsn=5.7.1, status=bounced (host mail.example.com[22.214.171.124] said: 553 5.7.1 email@example.com: Sender address rejected: not logged in (in reply to RCPT TO command))
Does anyone know who’s fault is that? Is my mail server the problem or the receipient’s mail server ?
