[Tutor] smtplib problems ?

[dave]

Hi all,

I am not sure if this is a Python problem not not but here goes....

I wrote the following small script to email by boss 'email_addr' a rather 
important reminder and also send a copy to myself 'email_addr2' several times 
a day. 




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


from smtplib import SMTP
from time import sleep
import sys


email_SMTP = 'mail.pusspaws.net'
email_addr = 'XXXX at chubb.co.uk'
email_addr2 = 'XXXX at pusspaws.net'


def email_remind():
  

    for trys in xrange(10):
        try:
                    
            mail_server = SMTP(email_SMTP)
            
            # email the office with a full email
            blog="""\n\nHi,\n\nHi,This is just a reminder, can you sort me out 
a date for my re-grade exam as soon as possible.
I have tied an email script into my cron (time scheduling) daemon to remind 
you an ever increasing number of times a day ;) - Got to love 
Linux\n\nCheers\n\nDave"""
            
            msg = ('Subject: Friendly reminder :)\r\nFrom: Dave Selby\r\nTo: 
'+\
            email_addr+'\r\n\r\n'+blog+'\r\n\r\n')
            
            mail_server.sendmail('Friendly reminder :)', email_addr, msg)
            mail_server.sendmail('Friendly reminder :)', email_addr2, 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)
    
email_remind()





It does the job (regrade exam now booked :)) but It succeeds in sending emails 
only about 50% of the time. The other 50% I get ...




Mailing error ... Re-trying ... 1 of 10

Mailing error ... Re-trying ... 2 of 10

Mailing error ... Re-trying ... 3 of 10

Mailing error ... Re-trying ... 4 of 10

Mailing error ... Re-trying ... 5 of 10

Mailing error ... Re-trying ... 6 of 10

Mailing error ... Re-trying ... 7 of 10

Mailing error ... Re-trying ... 8 of 10

Mailing error ... Re-trying ... 9 of 10

Mailing error ... Re-trying ... 10 of 10

Traceback (most recent call last):
  File "/home/dave/my files/andrew_torture/email_remind.py", line 49, in ?
    email_remind()
  File "/home/dave/my files/andrew_torture/email_remind.py", line 43, in 
email_remind
    raise 'Mail Failure\n'+str(sys.exc_type)+'\n'+str(sys.exc_value)
Mail Failure
smtplib.SMTPRecipientsRefused
{'XXXX at chubb.co.uk': (553, "sorry, that domain isn't in my list of allowed 
rcpthosts (#5.7.1)")}



I do not know if the is me not using the SMTP function correctly, I have 
noticed the emails arrive and kmail cannot work out when they were sent, or 
if the problem lies elsewear.

Any suggestions gratefully recieved

Cheers

Dave
