help with parsing email

[Ahmed, Shakir]

Thanks everyone who tried to help me to parse incoming email from an exchange server:

Now, I am getting following error; I am not sure where I am doing wrong. I appreciate any help how to resolve this error and extract emails from an exchange server. 


First I tried:
>>> mailserver = 'EXCHVS01.my.org'
>>> mailuser = 'myname'
>>> mailpasswd = 'mypass'
>>> mailserver = poplib.POP3(mailserver)
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "C:\Python24\lib\poplib.py", line 96, in __init__
    raise socket.error, msg
error: (10061, 'Connection refused')



The other way:

>>> mailserver = 'pop.EXCHVS01.ad.my.org'
>>> mailuser = 'myname at my.org'
>>> mailpasswd = 'mypass'
>>> mailserver = poplib.POP3(mailserver)
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "C:\Python24\lib\poplib.py", line 84, in __init__
    for res in socket.getaddrinfo(self.host, self.port, 0, socket.SOCK_STREAM):
gaierror: (11001, 'getaddrinfo failed')


I tried above ways but getting error

Thanks

Help from Maric Michaud [maric at aristote.info]

Three options here :

- dealing directly with outlook mailboxes files, I used some open source code 
to parse .pst files in past, but you'll need some googling to match your 
requirements. Doesn't help if there is an instance of outlook running on the 
box.

- use the outlook COM or even some windows MAPI interface via WIN32 API 
(pywin32), can't help with this one.

- access emails directly on the Exchange server via standard python modules 
poplib or imaplib, my preferred choice if one of these protocols are 
supported by your environment. You won't need no extensions, just a standard 
python installation, and your code will work with most mail delivery agent 
and will run on all python supported platform.


==========================
Help from Gabriel Genellina

I can't help with the part dealing with Outlook - but once you retrieved the email body, it's easy:

import re
re_number = re.compile(r"NoticeOfapplication/([0-9-_]+)")
match = re_number.search(body)
if match:
  print match.group(1)

(this matches any numbers plus "-" and "_" after the words NoticeOfapplication written exactly that way)
