Hello,
I'm trying to monitor my gmail account to know when I have obtained a
new email. It seems that once I have logged in, I should be able to
call the stat() function repeatedly to see how many messages are in my
inbox. The problem is that this number does not seem to update until I
have logged out, and logged back in. In other words, I run the code
below, send myself an email, and observe that the count does not
change. If I kill the program and restart (hence logging back in),
then the total count is now updated. The other function calls seem to
work the same way (eg "list" just shows the same list, even when I know
new mail has arrived).
Questions:
1. is this a standard behavior of pop protocol? (to give me the same
results for any API call on a single login?)
2. OR is this a peculiarity of gmail
3. is there a more efficient and correct way to see know when I have
received a new mail? Currently my "working" method is to log out and
log back in. With this method, I can get about 17 refreshes per minute
but anything faster and Gmail blocks me for a few minutes. (yes it is
important to my application that I have very frequent refreshes).
(see code sample below)
Thanks,
LJ

from email.Parser import Parser
parser = Parser()
server = poplib.POP3_SSL ("pop.gmail.com ", 995)
print server.user("XX X-MY_EMAIL")
print server.pass_("X XX-MY_PW")
server.set_debu glevel(0)
def getMsgCount():
# check message count by stat() and list() functions
numMsgs = server.stat()[0]
print "Num msg by stat():", numMsgs
print "Num msg by list():", len(server.list ()[1])
print "Most recent:", numMsgs, getSubj(numMsgs )
return
def getSubj(which):
# return subject of message with id 'which'
msg = "\n".join(serve r.top(which, 1)[1])
email = parser.parsestr (msg)
return email.get("Subj ect")
while True:
print "--"
getMsgCount()

Definitely POP3 standard behavior, as a simple reading of the relevant
RFC will show (e.g., http://www.ietf.org/rfc/rfc1939.txt):
summarizing... on entering Transaction state, a POP3 server acquires an
exclusive lock on the mailbox, to ensure that no modifications occur to
it throughout the session.
I'm not sure about the refresh frequency, but you may want to try the
Atom feed, https://mail.google.com/gmail/feed/atom .

Hello All,
Here's what I'm trying to do:
I need to connect to a pop3 server, download all messages, and copy all
of the attachments into a specific directory. The actual email message
is unimportant. Now, I've found plenty of examples that strip the
attachments from an email message, but most (if not all) of them take a
file parameter. My question is this:

For the poplib.POP3 object, docs say:

Request message list, result is in the form (response, ). If which is set, it is the message to list.

Is there any module or interface that allow the programmer to access a
imap4/pop3 server in a more pythonic (or Object Oriented) way than the
usual imaplib and popolib?
I mean: is there any module that would allow me to query the server for
specific messages (and fetch them) in a way similar to a OODB?
TIA

I've tried everything I can think of to specify SRVR in poplib:
"127.0.0.1:8081"
"127.0.0.1,port=8081"
"localhost:8081"
"localhost,port=8081"
and probably a few other things, but poplib can't see

I was wondering what methods you experts would reccomend for this task?
Here are the options I have come up with so far:
1. Build something with the poblib library
(http://docs.python.org/lib/module-poplib.html)
--Any pointers on doing this? How to I get poplib to save messages in
a standard format I can
later import into Thunderbird, Outlook, etc? (mbox?)

Hi there,
I am trying to use the poplib library to get emails using the retr
method. The small program bellow works but the message aren't flagged as
read which puzzles me. I believe the pop server is qmail 1.0.6 /
vpopmail 5.2.1 and I am running the following script on Windows using
Pyhton 2.5.

Hello,
I am writing a Python program to check email using POP3. I've tried
the sample code from python.org, and it works great. In other words,
the code below successfully prints out my emails.
import getpass, poplib, email
M = poplib.POP3('mail.blah.com')
M.user('username')
M.pass_('password')

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
