有没有人使用 Mailgun 帐户成功设置 msmtp？我不断收到“中继被拒绝”，并且 msmtp 报告来自的信封无效。我已经尝试了我能想到的发件人地址的所有变体，搜索了 Mailgun 的文档以获取有关其 SMTP 参数的详细信息，并在网上搜索示例，但我没有发现任何与我的设置不同的东西（除了服务器和帐户名字，当然）。

这是我的/etc/msmtprc文件，

account default

# The SMTP smarthost
host smtp.mailgun.org

# Use TLS on port 465
port 465
tls on
tls_starttls off

user manul@mail.mydomain.net
password [snip]

from mailgun@mydomain.net

# Syslog logging with facility LOG_MAIL instead of the default LOG_USER
syslog LOG_MAIL

和 msmtp 会话：

$ echo 'Subject: Grfg' | msmtp -v 'aidalgol@example.net'
loaded system configuration file /etc/msmtprc
ignoring user configuration file /home/me/.msmtprc: No such file or directory

原来是我需要auth on在msmtp配置中设置。msmtp的错误envelope from address mailgun@mydomain.net not accepted by the server是完全错误的。
