Hello! In the network I have many thunderbird-clients. They can send all messages outside the domain. I also use squirrelmail, but i have the problem when sending a mail outside the domain. Postfix answers: 554 Relay access denied Errorlog says: Sep 14 17:15:36 mail postfix/smtpd[11195]: connect from domain[127.0.0.1] Sep 14 17:15:36 mail postfix/smtpd[11195]: NOQUEUE: reject: RCPT from domain[127.0.0.1]: 554 <mail@xxxx>: Relay access denied; from=<edv@xxxxxxxxxxxxxx> to=<mail@xxxx> proto=ESMTP helo=<mail.btw> Sep 14 17:15:36 mail postfix/smtpd[11195]: lost connection after RCPT from mail.btw[127.0.0.1] Sep 14 17:15:36 mail postfix/smtpd[11195]: disconnect from mail.btw[127.0.0.1] In Thunderbird i use SENDING with Authentication and "TLS if available", and it works fine. I tried to set the smtp-Server to the "domain-Name" and the smtp-auth-mech to "login" and also to use_smtp_tls with "true", but nothing worked. So do you have any idea?
