我正在尝试使用 Postfix 通过 Amazon SES 在具有 Internet 连接的本地服务器上从我的应用程序发送电子邮件。我在 SES 沙盒上有一个经过验证的“收件人”电子邮件地址。但是，每当我尝试发送邮件时，它都无法发送电子邮件，以下是/var/log/mail.log的内容：

以下是我的postfix配置文件/etc/postfix/main.cf
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = zzzz.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = zzzz.com
relayhost = [email-smtp.us-east-1.amazonaws.com]:587
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
inet_protocols = all
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
我遵循了 AWS 指南中给出的所有步骤，但这似乎不起作用，如果有人可以帮助我解决这个问题。
干杯!
