I have some executives that refuse to use exchange and insist on using postfix.
So I setup a postfix server for them. I have tested this postfix server and it works perfectly using thunder bird. Here is a successful message:
Mar 27 21:41:15 XXXXpostfix01 postfix/smtp: A5B1B21694: to=<firstname.lastname@example.org>, relay=gmail-smtp-in.l.google.com[184.108.40.206]:25, delay=1.3, delays=0.65/0/0.12/0.56, dsn=2.0.0, status=sent (250 2.0.0 OK 1332946033 np1si3148089igc.2)
Now when the executives use the postfix server it fails:
Mar 29 06:55:53 XXXXpostfix01 postfix/smtpd: NOQUEUE: reject: RCPT from unknown[220.127.116.11]: 554 5.7.1 <XXXXllc@gmail.com>: Recipient address rejected: Relay access denied; from=<XXXtest@mydomain.com> to=<XXXXllc@gmail.com> proto=SMTP helo=<SonyXXXXX.mydomain.com>
These users refuse to tell me what mail client they are using. But only differance I see is they are using IMAP 554 and they got a different IP for MX record on DNS.
I am stumped help!
