Subject line not coming in the smtp mail sent from python

问题

My code is running and sending the mail. But To and Subject are not coming in the mail. Here is a snippet of the code i used. What could be the issue?

Code :

   username = "N@EXAMPLE.com"
   password = "fnEOFINO”


   print("Logged in")

   sender = 'n@example.com'
   receivers = 'T@example.com'
   message = """From: Neeraja Rajiv  <NRajiv@EXAMPLE.com>
   To: T@EXAMPLE.COM 
   Subject: SMTP e-mail test

   Overall
   %d
                                               """%(variable)
   print("Connecting to server")

   server = smtplib.SMTP('SMTP-********.com', 25)
   print("Connected to server")
   server.set_debuglevel (1)
   server.sendmail(sender,receivers,message)         
   print ("Successfully sent email")

In the Email, subject is missing.

Any approaches/suggestions are most welcome.

I think your problem lies in how you have created your message, the corrected version works using it with the example code below:

msg = """From: 'From Neeraja Rajiv  <NRajiv@EXAMPLE.com>'
To: 'To Toffet Joseph - Consultant <TJoseph@EXAMPLE.com>'
Subject: 'SMTP e-mail test'
Overall'{}'""".format(variable)

username = "foo"
password = "bar"

print("Logged in")

import smtplib
sender = "foo@gmail.com"
receivers = "bar@gmail.com"
msg = """From: 'From Neeraja Rajiv  <NRajiv@EXAMPLE.com>'
To: 'To Toffet Joseph - Consultant <TJoseph@EXAMPLE.com>'
Subject: 'SMTP e-mail test'"""

server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.ehlo()
server.login(username, password)
server.sendmail(sender, receivers , msg)
server.quit()

Padraic Cunningham example looks correct. Here is another example. Maybe this might help...

Sample Email To SMTP Server Python Script:

import smtplib

try:

host = '?.?.?.?'                                              #The Address To Your SMTP Server...
port = 25

to = 'reciever@someplace.com'                                 #Reciever Of Email...
from_addr = 'sender@someplace.com'                            #Sender Of Email...

subject = '<YOUR SUBJECT HERE>'                               #Subject Of Email...

text_line_1 = 'Body Line 1...\r\n'                            #Body Of Email...
text_line_2 = '\r\n'
text_line_3 = 'Body Line 3...\r\n'
text_line_4 = '\r\n'
text_line_5 = 'Body Line 5...\r\n'

total_message = text_line_1 + text_line_2 + text_line_3 + text_line_4 + text_line_5 

msg = "From: %s\nTo: %s\nSubject: %s\n\n%s" % (from_addr, [to], subject, total_message)

server = smtplib.SMTP(host, port)
server.sendmail(from_addr, to, msg)

print('Successfully Sent Email...')

except Exception as e: print('Exception: ' + str(e))

Good Luck...
