With mailx, if you send the email to an Outlook user, you can add 2 spaces at the beginning of each line.
使用mailx，如果您将电子邮件发送给 Outlook 用户，则可以在每行开头添加 2 个空格。
{ echo "Hi xxx, would you tell me something" ; echo "thanks!" ; echo "-xxx" } | sed 's/^/ /g' | mailx -s "subject" [email protected]

I encountered this issue and resolved it by surrounding with quotes the variable I was piping into mailx.
我遇到了这个问题，并通过用引号括住我正在输入的变量来解决它mailx。
I started with a list of processes from ps i.e. list="$(ps |grep some_process)".
我从 ps ie 中的进程列表开始list="$(ps |grep some_process)"。
Then when I tried to mail that out as follows, the newlines were obliterated:
然后，当我尝试按如下方式将其邮寄出去时，换行符被删除了：
echo $body | mailx -s "${subject}" [email protected]
But, simply wrapping $bodywith quotes preserved the newlines:
但是，只需$body用引号包裹即可保留换行符：
echo "$body" | mailx -s "${subject}" [email protected]
