Mutt 默默地无法发送电子邮件。没有错误或失败。但有时邮件发送成功，有时却发送失败。
这就是我在一项任务中安装所有必需的可安装文件/库的方式。
sudo apt-get update
sudo apt install snapd
sudo snap install okular
sudo apt install mailutils
sudo apt install mutt
在另一项任务中，我发送这样的电子邮件：
url=https://dev.azure.com/xyz/project/_build/results?buildId=$(Build.BuildId)
echo -e "$url"
mutt -v
echo -e "Hello All,\n\n Please find inline as well as attached the elaborative test results which $(Agent.JobStatus) and generated \n\nRegards\nQA Team\n\nLink to Azure DevOps Pipeline Build : $url-- [email protected]
以下是发送邮件的日志。我在这里没有看到任何错误。

可能是什么原因？设置在 Ubuntu 20.04 上
答案1
在您的示例中，您没有发送包含 mutt 的电子邮件，您正在运行mutt -v（显示 mutt 的版本和编译详细信息），然后您正在运行echo.
如果你想用 mutt 发送消息，你可以这样做：
mutt -s "subject" [email protected] <<__EOF__
Hello All,
Please find inline as well as attached the elaborative test results which $(Agent.JobStatus) and generated
Regards
QA Team
Link to Azure DevOps Pipeline Build : $url
__EOF__
您可以使用echo或printf或其他任何方式将消息通过管道传输到 中mutt，但由于消息中嵌入了多个换行符，因此使用heredoc更容易。
man mutt有关 mutt 命令行选项的更多详细信息，请参阅参考资料 - 例如，您可以使用-a filenameMIME 附加文件、-i filename将文件包含在消息正文中、-c用于 CC 和-bBCC。
