这是 sm.py

import logging
import smtplib
import sys
from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart


      try:
         smaid = qs[0].id
         gmailUser = 'no-reply@xxxxxxxxxxx.com'
         gmailPassword = '12345'
         mailServer = smtplib.SMTP('smtp.gmail.com', 587)
         mailServer.ehlo()
         mailServer.starttls()
         mailServer.ehlo()
         mailServer.login(gmailUser, gmailPassword)

         to_addr = "xxxxx@xx.com"
         subject = sys.argv[1]
         body = sys.argv[2]
         try:
             msg = MIMEMultipart()
             msg['From'] = gmailUser
             msg['To'] = to_addr
             msg["Content-type"] = "text/html"
             sub = subject
             msg['Subject'] = sub
             body = body

             msg.attach(MIMEText(body, 'html'))
             mailServer.sendmail(gmailUser, to_addr, msg.as_string())
         except:
             write_exception("send exception")

         mailServer.close()
     except:
          write_exception("send exception1")

如果您坚持发送 HTML，则需要 HTML 换行符：

import cgi
# escape special HTML characters
body = cgi.escape(body)
# use HTML line breaks
body = body.replace("\r\n", "\n").replace("\n", "<br />\n")

但可能你既不需要 Multipart 也不需要 HTML，所以你可以使用smtplib.SMTP.sendmail：

headers = (('From', gmailUser), 
           ('To', to_addr), 
           ('Subject', subject))

# normalize newlines to CR+LF, as required by SMTP
body = body.replace("\r\n", "\n").replace("\n", "\r\n")

msg = '\r\n'.join("%s: %s" % kv for kv in headers) + '\r\n'*2 + body

mailServer.sendmail(gmailUser, [to_addr], msg)

此外，您不应通过命令行提供文件内容，因为命令行是有长度限制的。相反，您应该通过 STDIN 提供文件，例如 inpython ... < /tmp/alert.txt并通过

import sys
body = sys.stdin.read()

发送它text/plain而不是text/html. 您那里没有任何 HTML。那应该可以解决它，因为然后由客户来正确显示文本。新行在 HTML 中没有相同的效果。

您将邮件的内容类型设置为“text/html”，因此用户的邮件代理显然会将正文解释并呈现为 html。如果要保留纯文本格式，请不要将内容类型设置为 text/html。

你用的是哪个外壳？

"`cat xxx`"

在 csh 中将删除所有换行符并返回一个空格分隔的字符串

> cat >testfile
line 1
line 2
<ctrl-d>
> echo "`cat testfile`"
line 1 line 2
