I'm not sure if you are able to bypass Outlook (and have Python fetch the
mail itself using poplib), but if you are, the following code might be
useful. I use this to pry apart emails which might contain multiple MIME parts.
from email.Parser import Parser
from rfc822 import parseaddr
import poplib
import smtplib
popserver="pop.site.com"
popuser="[EMAIL PROTECTED]"
poppassword="secret"
# split a message into an header- and body part
def separate(msg):
if isinstance(msg,str):
msg=msg.split('\n')
emptyline=msg.index('')
return msg[:emptyline],msg[emptyline+1:]
# return a certain headerline from the headers
def headerline(header,tag="From: "):
for h in header:
if h.startswith(tag):
return h[len(tag)+1:]
return ""
# enumerate recursively the contents of a MIME message
# remember the first text/plain and text/html part(s) that is found
# also remember if any other parts were found (like attachments)
#
def enummimeparts(msg,extract,level=1,verbose=False):
m=Parser().parsestr(msg)
if m.is_multipart():
if verbose: print '\t'*level,'multipart'
for part in m.get_payload():
enummimeparts(part.as_string(),extract,level+1,verbose)
else:
t=m.get_content_type()
if verbose: print '\t'*level,t
if t=="text/plain":
if not "text/plain" in extract:
headers,body=separate(m.as_string())
extract["text/plain"]='\n'.join(body)
else:
extract["others"]=True
elif t=="text/html":
if not "text/html" in extract:
headers,body=separate(m.as_string())
extract["text/html"]='\n'.join(body)
else:
extract["others"]=True
else:
extract["others"]=True
# extract the first 'text/plain' and 'text/html' mime-parts from a message
def extracttext(msg):
extract={}
enummimeparts(msg,extract)
return
extract.get("text/plain",None),extract.get("text/html",None),extract.get("ot
hers",False)
def processmessage(msgnr):
# get a message from the POP server, extract the parts
response,lines,bytes=pop.retr(msgnr)
msg='\n'.join(lines)
headers,body=separate(lines)
name,fromaddress=parseaddr(headerline(headers,"From:"))
subject=headerline(headers,"Subject:")
logging.info(subject+" ("+fromaddress+")")
(plain,html,others)=extracttext(msg)
# prefer flat text; if not present in the message, fallback to HTML
content (if any)
texttoprocess=""
if plain:
texttoprocess=plain
elif html:
texttoprocess=html
# now do something useful with the text
processtext(texttoprocess)
# delete message from pop server after processing
pop.dele(msgnr)
# connect to the pop server and process all messages
logging.info("Checking pop server '%s', user '%s'" % (popserver,popuser))
pop=poplib.POP3(popserver)
pop.user(popuser)
pop.pass_(poppassword)
stat=pop.stat()
if stat[0]:
for n in range(stat[0]):
processmessage(n+1)
pop.quit()
