I am attempting to use the python 3.2 SMTPlib.sendmail() function to send a message, after some modifcation of the SMTP library (namely commenting out the rset() function which was suppressing the error msg) I managed to retrieve the following error message from the server:
SendMail Failed (554, b'Transaction failed : Cannot send message due to possible abuse; please visit http://postmaster.yahoo.com/abuse_smtp.html for more information')
The yahoo mail SMTP server thinks I'm sending spam, the URL does link to anything useful. I think it has to do with an inadequate header, I can't seem to find a definitive answer on what constitutes a compliant header & I've read of simmilar issues with Gmail. Mock emails have been substituted for this post.
Any help would be appreciated
My full code is below:
self.message = email.message_from_string('''To: <ksmith@yahoo.co.nz>
From: <rwilson@yahoo.co.nz>
Reply-To: <rwilson@yahoo.co.nz>
Subject: Test send mail \n\n Hello''')
fromAddress = 'rwilson@yahoo.co.nz'
toAddress = 'ksmith@yahoo.co.nz'
try:
self.smtp = SMTP()
self.smtp.connect('smtp.mail.yahoo.com')
except Exception:
print('Connection Failed')
print(traceback.format_exc())
try:
self.smtp.login('rwilson','tree22')
except Exception:
print('Login Failed!')
print(traceback.format_exc())
try:
self.smtp.sendmail(fromAddress,toAddress ,self.message.as_string())
print("Message sucessfully sent!")
self.smtp.close()
except Exception as e:
print('SendMail Failed')
print(e)
The following works for microsoft, google, yahoo accounts on Python 2.7 and Python 3.2:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""Send email via smtp_host."""
import smtplib
from email.mime.text import MIMEText
from email.header import Header
####smtp_host = 'smtp.live.com' # microsoft
####smtp_host = 'smtp.gmail.com' # google
smtp_host = 'smtp.mail.yahoo.com' # yahoo
login, password = ...
recipients_emails = [login]
msg = MIMEText('body…', 'plain', 'utf-8')
msg['Subject'] = Header('subject…', 'utf-8')
msg['From'] = login
msg['To'] = ", ".join(recipients_emails)
s = smtplib.SMTP(smtp_host, 587, timeout=10)
s.set_debuglevel(1)
try:
s.starttls()
s.login(login, password)
s.sendmail(msg['From'], recipients_emails, msg.as_string())
finally:
s.quit()
Add the following to your code before logging in and have a try again;
try:
self.smtp.ehlo()
self.smtp.starttls()
self.smtp.ehlo
except:
print "No TLS :("
#do login here
