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

我可以阅读收到的邮件，但不能发送。

如果我使用 telnet localhost 25 连接，我可以发送外部电子邮件，但使用 Outlook 客户端它不起作用。

这是我的 postfix 和 dovecot 配置：

postconf -n

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
inet_interfaces = all
mailbox_size_limit = 0
mydestination = localhost
myhostname = mail.mydomain.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_path = private/auth
smtpd_sasl_type = dovecot
smtpd_tls_auth_only = yes
smtpd_tls_cert_file = /etc/ssl/certs/dovecot.pem

有什么想法吗？

如果您使用比 2.10 更新的后缀版本，那么您需要按照此处smtpd_relay_restrictions所述添加选项：

# 对于 Postfix 2.10 及更高版本，邮件中继策略为
# 最好在 smtpd_relay_restrictions 下指定。
/etc/postfix/main.cf：
    smtpd_relay_restrictions =
    permit_mynetworks
    permit_sasl_authenticated
    拒绝_unauth_destination

# 较旧的配置结合了中继控制和垃圾邮件控制
# smtpd_recipient_restrictions。将此示例与 Postfix 一起使用 ≥
# 2.10 指定“smtpd_relay_restrictions=”。
/etc/postfix/main.cf：
    smtpd_recipient_restrictions =
    permit_mynetworks
    permit_sasl_authenticated
    拒绝_unauth_destination
        ...其他规则...

之后，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。

对于我在 Amazon AWS EC2 上的 postfix 2.6.6，结果证明我在 main.cf 中配置了错误的“mydestination”和“relay_domains”设置。正确的值（对我有用的值）是：

mydestination = $myhostname, $mydomain, localhost relay_domains = $mydestination
