A particular mailer, slightly broken, cannot send mail to a postfix (2.7.0) box:
Feb 5 08:51:16 pizza postfix/smtpd[30453]: NOQUEUE: reject: RCPT from chocolate .egps.com[38.119.130.7]: 450 4.1.8 <nob...@vps.jewishwomansonlinecalendar.com>: Sender address rejected: i Domain not found; from=<nob...@vps.jewishwomansonlinecalendar.com> to=<sample@domain.example> proto=ESMTP helo=<chocolate.egps.com> Where the sample@domain.example is a valid address on the local machine. What's the easiest to let this mail through? I tried adding the domain to /var/spool/postfix/etc/hosts, and it didn't help. Thanks!
