Linux postfix/dovecot 554中继访问被拒绝

问题描述

尝试从Outlook客户端发送电子邮件时出现此错误554 Relay access denied.

I have this error 554 Relay access denied when trying to send email from my outlook client.

我可以阅读传入的邮件，但不能发送.

I can read incoming mails but cannot send.

如果我使用telnet localhost 25可以连接外部电子邮件，但是使用Outlook Client则无法使用.

If i connect with telnet localhost 25 i can send external emails, but with outlook client it doesn't work.

这是我的postfix和dovecot配置:

Here's my postfix and dovecot config :

postconf -n

  driver = static
}
userdb {

有什么想法吗?

推荐答案

如果您使用的是2.10以后的后缀版本，则需要按照此处:

If you use a postfix version newer then 2.10, then you need to add the smtpd_relay_restrictions option as described here:

# With Postfix 2.10 and later, the mail relay policy is
# preferably specified under smtpd_relay_restrictions.
/etc/postfix/main.cf:
    smtpd_relay_restrictions =
    permit_mynetworks
    permit_sasl_authenticated
    reject_unauth_destination

# Older configurations combine relay control and spam control under
# smtpd_recipient_restrictions. To use this example with Postfix ≥
# 2.10 specify "smtpd_relay_restrictions=".
/etc/postfix/main.cf:
    smtpd_recipient_restrictions =
    permit_mynetworks
    permit_sasl_authenticated
    reject_unauth_destination
        ...other rules...

此后，任何经过sasl身份验证的用户都应该能够使用smtp通过服务器发送邮件.

After that, any sasl authenticated user should be able to send mails through the server using smtp.
