postfix-mta - 后缀 SMTP 550 5.7.60 SMTP

Question

我在带有后缀的 Ubuntu 20.04 上运行请求跟踪器 5，但我无法从 RT 发送电子邮件。当我发送测试电子邮件时，它可以工作。这是我的main.cf文件

smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

smtp_sasl_security_options = noanonymous

smtp_sasl_type = cyrus

smtp_sasl_mechanism_filter = login

smtp_sender_dependent_authentication = yes

sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay

smtp_generic_maps = hash:/etc/postfix/generic

smtp_tls_CAfile = /etc/postfix/cacert.pem

smtp_use_tls = yes

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = localhost
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
relayhost = mail.example.com:587
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
inet_protocols = all

和我的日志/var/log/mail.log
