使用 TLS 和身份验证问题的 SMTP 服务器邮件警报

Question

我对在 AIX 7.1 OS 上使用 SMTP 服务器警报配置有点陌生。我目前正在使用以下运行良好的语法：

import sys

from PySide2.QtCore import QThread, QMutex
from PySide2.QtGui import QPixmap
from PySide2.QtWidgets import QApplication, QVBoxLayout, QWidget, QPushButton, QHBoxLayout, QLabel

from API import API

class MainWindow(QWidget):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.init_UI()


    def init_UI(self):
        self.setFixedSize(690, 530)
        self.image_lbl = QLabel()

        self.image_lbl.setPixmap(QPixmap("img/im.jpg"))

        btn_cnt = QPushButton("Continue")
        btn_pa = QPushButton("Pause")

        hbox = QHBoxLayout()
        hbox.addWidget(btn_cnt)
        hbox.addWidget(btn_pa)

        vbox = QVBoxLayout()
        vbox.addWidget(self.image_lbl)
        vbox.addLayout(hbox)

        self.setLayout(vbox)

        self.start_api()
        self.show()


    def start_api(self):
        self.thread_API = QThread()
        self.api = API()
        self.api.moveToThread(self.thread_API)
        self.thread_API.started.connect(self.api.start)
        self.api.signal_get_value.connect(self.read_measurement)

        self.thread_API.start()
        # ToDo: Do I need the terminate thread when exited from the app?

    dv = 0
    def read_measurement(self):
        measurement = None
        result = "measurement " + str(self.dv)
        self.dv += 1
        self.api.data.set_measurement(result)
        self.api.pause = False



if __name__ == '__main__':
    app = QApplication(sys.argv)
    main_form = MainWindow()
    sys.exit(app.exec_())

但我们现在正在迁移我们的 SMTP 服务器并启用身份验证和 TLS，但我无法这样做。请指导我我做错了什么：

mail -s "Subject" "abc@test.com" < /path/to/my/input.txt

我得到的错误是：

echo "This is the message body and contains the message" | mailx -v -s "This is the subject" -S smtp=smtp://newsmptp.test.com:25 -S smtp-use-starttls -S smtp-auth=login -S smtp-auth-user="temp" -S smtp-auth-password="Abc#123" -S ssl-verify=ignore "abc@test.com
