[Tutor] smtplib mail header problem

[Liam Clarke-Hutchinson]

Hi Dave, 

IIRC The first argument to sendmail() is the name of the account that's
sending... So when you include your subject there, it seems your ISP is
somewhat forgiving.

Subject: [Tutor] smtplib mail header problem


Hi all,

I have a python script that works out & emails my employer with parts that I

have used. It has been great for 11ish months, now all my mail is classed as

spam & junked :(

Apparently the reason for it being junked is ...

'No subject' and 'No Sender'

I set up a small test script to isolate the problem using the core of the 
email code ...


#!/usr/bin/env python
# -*- coding: iso8859_1 -*- 


from smtplib import SMTP
from time import sleep, strftime
from datetime import datetime
import sys


email_SMTP = 'mail.pusspaws.net'
email_addr = 'jk at pusspaws.net'


def email_test():
  

    for trys in xrange(10):
        try:
                    
            mail_server = SMTP(email_SMTP)
            mail_server.login('XXXX', 'XXXX')
            
            
            subject = 'Test Email'
            from_ = 'Dave Selby<chubb at pusspaws.net>'
            to = email_addr
            return_path = email_addr
            
            blog="""Hi,\n\nThis is just a test"""
            
            msg = mail_headers(subject, from_, to, return_path) 
+'\r\n\r\n'+blog
            
            mail_server.sendmail(subject , email_addr, msg)
            
            mail_server.quit()
            
            # If we get to here, all is well, drop out of the loop
            break
            
        except:
            print 'Mailing error ... Re-trying ... '+str(trys+1)+' of 10\n'
            sleep(300)
            
    if trys==9:
        raise 'Mail Failure\n'+str(sys.exc_type)+'\n'+str(sys.exc_value)
    
    
    
    

def mail_headers(subject, from_, to, return_path):
    """
    Generate a formatted mail header string
    """
    
    header = 'Return-Path: ' + return_path 
    header = header + '\r\nFrom: ' + from_
    header = header + '\r\nReply-To: ' + return_path
    header = header + '\r\nTo: ' + to
    header = header + '\r\nSubject: '+subject

    now=datetime.now()

    day = now.strftime('%a')
    date = now.strftime('%d %b %Y %X')
    
    header = header + '\r\nDate : ' + day + ', ' + date + ' -0000\r\n'
    
    return (header)

    
email_test()



>From this I receive the following ....

Hi,

This is just a test


I cannot seem to set the top 'Return-path' correctly, any ideas how I do 
this ? also I have a sender so I am unsure why the spam filter picked this 
out.

Any suggestions

Cheers

dave
