echo "this is the body" | mail -s "this is the subject" "to@address"

在MAC操作系统或Linux操作系统的终端上输入这段代码

mail -s (subject) (receiversEmailAddress)  <<< "how are you?"

举个例子

mail -s "hi" abc@example.com <<< "how are you?"<br>

我认为斯威克斯是最好的。这里有一个更复杂的例子，在端口25上使用TLS加密:

swaks --from john.smith@mydomain.com \
--h-From: '"John Smith" <john.smith@mydomain.com>' \
--h-Subject: 'Subject of message' \
--auth LOGIN --auth-user mylogin --auth-pass mypass \
--to someone@otherdomain.com \
--server smtp.example.com --port 25 -tls \
--add-header 'Content-Type: text/plain; charset="utf-8"'

如果你只需要一个主题行(就像在一个警告消息中一样)，简单地做:

mailx -s "This is all she wrote" < /dev/null "myself@myaddress"

echo "this is the body" | mail -s "this is the subject" "to@address"

对于SMTP主机和Gmail，我喜欢使用Swaks -> https://easyengine.io/tutorials/mail/swaks-smtp-test-tool/

在Mac上:

酿造安装swaks Swaks—到user@example.com—服务器smtp.example.com
