Help on Postfix Problem.
I have postfix installed on Centos... and have a little problem... Postfix is running fine (I think), coz I can send and receive email via Squirrel Mail...
The problem is using Outlook Express, here is the error in Outlook Express:
Sending Error:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'lucasharoldvn@yahoo.com'. Subject 'test', Account: 'mail.domain.com', Server: 'mail.domain.com', Protocol: SMTP, Server Response: '554 <lucasharoldvn@yahoo.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
Reading/Downloading Email Error:
The connection to the server has failed. Account: 'mail.domain.com', Server: 'mail.domain.com', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E
Note: mail.domain.com replaced the original mail server address.
And here is the error message in /var/logl/maillog:
postfix/smtpd[14516]: connect from unknown[xx.xx.xx.xx]postfix/smtpd[14516]: NOQUEUE: reject: RCPT from unknown[xx.xx.xx.x]: 554 <lucasharoldvn@yahoo.com>: Relay access denied; from=<user@domain.com> to=<lucasharoldvn@yahoo.com> proto=ESMTP helo=<pc>
postfix/smtpd[14516]: disconnect from unknown[xx.xx.xx.xx]
Note : xx.xx.xx.xx replaced my local ip add; user@domain.com replaced my email add in the mail server.
Any body can help?
Thanks
