parsing downloaded mail via POP3

[Kevin F]

I have the following script:

emails = []
for msg in messagesInfo:
msgNum = int(msg.split()[0])
msgSize = int(msg.split()[1])
if(msgSize < 20000):
message = server.retr(msgNum)[1]
Message = join(message, “\n”)
emails.append(message)
It downloads messages for me via my POP3 server, however, the message
format (attached below) includes ridiculous amounts of data and I just
want to return the from, subject, and body. Any pointers on how to do this?

Have you tried server.top ?

MAX_SUMMARY_LINES = 20

def get_headers(self):
server = poplib.POP3(self.server_name)
server.user(self.user_name)
server.pass_(self.password)
hdrs = []
try:
msgCount, msgBytes = server.stat()
for i in range(msgCount):
msgNum = i+1
hdr, message, octets = server.top(msgNum,
MAX_SUMMARY_LINES)
hdrs.append(message)
finally:
server.quit()

alternatively, something like:
import poplib, email
from email.Utils import getaddresses, parseaddr

def download_mail(self):
server = poplib.POP3(self.server_name)
server.user(self.user_name)
server.pass_(self.password)
try:
msgCount, msgBytes = server.stat()
self.messages = []
for i in range(msgCount):
msgNum = i+1
hdr, message, octets = server.retr(msgNum)
mail_msg = '\n'.join( message)
self.messages.append(
email.message_from_string(mail_msg) )
finally:
server.quit()

def print_headers(self):
for message in self.messages:
print '#' * 80
print parseaddr( message['from'] )
print message['subject']
print message['date']
print getaddresses( message.get_all('to', []) )
print getaddresses( message.get_all('cc', []) )
