Counting Messages in IMAP Folders in Python

Posted on November 29, 2012 by Jonathan Franzone

Continuing on my last post (), I wanted to show a snippet of Python code that will list a set of IMAP folders and count the number of messages in them. You give it a starting folder and it lists that folder plus all/any sub-folders and their message counts. At the very end it prints a total message count.

from imaplib import IMAP4, IMAP4_PORT
import sys, traceback

# Your IMAP Settings
host = ''
port = IMAP4_PORT
user = ''
password = ''
folder = 'INBOX'

imap = None

def parse_mailbox(data):
    flags, b, c = data.partition(' ')
    separator, b, name = c.partition(' ')
    return (flags, separator.replace('"', ''), name.replace('"', ''))

try:
    # Create the IMAP Client
    imap = IMAP4(host, port)
    # Login to the IMAP server
    resp, data = imap.login(user, password)
    if resp == 'OK' and bytes.decode(data[0]) == 'LOGIN completed':
        totalMsgs = 0
        # Get a list of mailboxes
        resp, data = imap.list('"{0}"'.format(folder), '*')
        if resp == 'OK':
            for mbox in data:
                flags, separator, name = parse_mailbox(bytes.decode(mbox))
                # Select the mailbox (in read-only mode)
                imap.select('"{0}"'.format(name), True)
                # Get ALL message numbers
                resp, msgnums = imap.search(None, 'ALL')
                mycount = len(msgnums[0].split())
                totalMsgs = totalMsgs + mycount
                print('{:<30} : {: d}'.format(name, mycount))
            print('{:<30} : {: d}'.format('TOTAL', totalMsgs))
except:
    print('Unexpected error : {0}'.format(sys.exc_info()[0]))
    traceback.print_exc()
finally:
    if imap != None:
        imap.logout()
    imap = None

from imaplib import IMAP4, IMAP4_PORT

import sys, traceback

# Your IMAP Settings

host = ''

port = IMAP4_PORT

user = ''

password = ''

folder = 'INBOX'

imap = None

def parse_mailbox(data):

flags, b, c = data.partition(' ')

separator, b, name = c.partition(' ')

return (flags, separator.replace('"', ''), name.replace('"', ''))

try:

# Create the IMAP Client

imap = IMAP4(host, port)

# Login to the IMAP server

resp, data = imap.login(user, password)

if resp == 'OK' and bytes.decode(data[0]) == 'LOGIN completed':

totalMsgs = 0

# Get a list of mailboxes

resp, data = imap.list('"{0}"'.format(folder), '*')

if resp == 'OK':

for mbox in data:

flags, separator, name = parse_mailbox(bytes.decode(mbox))

# Select the mailbox (in read-only mode)

imap.select('"{0}"'.format(name), True)

# Get ALL message numbers

resp, msgnums = imap.search(None, 'ALL')

mycount = len(msgnums[0].split())

totalMsgs = totalMsgs + mycount

print('{:<30} : {: d}'.format(name, mycount))

print('{:<30} : {: d}'.format('TOTAL', totalMsgs))

except:

print('Unexpected error : {0}'.format(sys.exc_info()[0]))

traceback.print_exc()

finally:

if imap != None:

imap.logout()

imap = None

Listing IMAP Mailboxes with Python

Posted on November 24, 2012 by Jonathan Franzone

I’ve been working on some Python scripts recently to manage my IMAP mailboxes and the information I found on the internet was fairly good, but lacked a completeness that my newbie Python skills required. So, I figured I’d post a complete example to list mailboxes (folders) for your IMAP account. This was developed using Python 3.3.

import imaplib
import sys
import traceback

# Your IMAP Settings
host = ''
port = 143
user = ''
password = ''

imap = None

'''
parse_mailbox() will extract the three pieces of information from
the items returned from a call to IMAP4.list(). The initial data
array looks like:
[b'(\\HasChildren) "/" NameOfFolder', ...]
At least on my server. If the folder name has spaces then it will
be quote delimited.
'''
def parse_mailbox(data):
    flags, b, c = data.partition(' ')
    separator, b, name = c.partition(' ')
    return (flags, separator.replace('"', ''), name.replace('"', ''))

try:
    # Create the IMAP Client
    imap = imaplib.IMAP4(host, port)
    # Login to the IMAP server
    resp, data = imap.login(user, password)
    if resp == 'OK' and bytes.decode(data[0]) == 'LOGIN completed':
        # List all mailboxes
        resp, data = imap.list('""', '*')
        if resp == 'OK':
            for mbox in data:
                flags, separator, name = parse_mailbox(bytes.decode(mbox))
                fmt = '{0}    : [Flags = {1}; Separator = {2}'
                print(fmt.format(name, flags, separator))
except:
    print('Unexpected error : {0}'.format(sys.exc_info()[0]))
    traceback.print_exc()
finally:
    if imap != None:
        imap.logout()

import imaplib

import sys

import traceback

# Your IMAP Settings

host = ''

port = 143

user = ''

password = ''

imap = None

'''

parse_mailbox() will extract the three pieces of information from

the items returned from a call to IMAP4.list(). The initial data

array looks like:

[b'(\\HasChildren) "/" NameOfFolder', ...]

At least on my server. If the folder name has spaces then it will

be quote delimited.

'''

def parse_mailbox(data):

flags, b, c = data.partition(' ')

separator, b, name = c.partition(' ')

return (flags, separator.replace('"', ''), name.replace('"', ''))

try:

# Create the IMAP Client

imap = imaplib.IMAP4(host, port)

# Login to the IMAP server

resp, data = imap.login(user, password)

if resp == 'OK' and bytes.decode(data[0]) == 'LOGIN completed':

# List all mailboxes

resp, data = imap.list('""', '*')

if resp == 'OK':

for mbox in data:

flags, separator, name = parse_mailbox(bytes.decode(mbox))

fmt = '{0} : [Flags = {1}; Separator = {2}'

print(fmt.format(name, flags, separator))

except:

print('Unexpected error : {0}'.format(sys.exc_info()[0]))

traceback.print_exc()

finally:

if imap != None:

imap.logout()

I hope this code snippet help you on your way to Python IMAP goodness. If not, it will at least server as a reminder to myself the next time I need to do something like this.

The Gunslinger

Posted on January 5, 2012 by Jonathan Franzone

I just finished listening to The Gunslinger, the first book in the Dark Tower series by Stephen King. This series made it onto my potential reading list because of the suggestion of Scott Johnson, a web cartoonist who also has several podcasts which I enjoy (The Instance, Film Sack!) I am currently training for a marathon, so my weekend runs are fairly long (in the multiple hour range) and I decided it would be a good opportunity to listen to some audiobooks. I just picked The Gunslinger from my list because I had the audiobook and it seemed like a good place to start.

So how did I like it? It was really good. You can look it up and read all about it, so I won’t rehash the details of the novel and what it is about. The thing I liked was that it mixed so many different genres. It is a cowboy western with some sorcery/magic mixed in. There is also a “knights of the round table” feel and some modern day sci fi. Throw in some religion (a somewhat blasphemous take on Christianity no less – not my favorite part) and multiple/parallel universe thinking and you have yourself a mixed up jumble of interesting reading (or listening in my case).

Hey Microsoft, Where Are My Keyboard Shortcuts!?

Posted on August 19, 2011 by Jonathan Franzone

Delete Key I recently upgraded to Microsoft Office 2010. I really like the way the design team is going on their newer versions. It is really sleek and nice feeling, but I’ve noticed something missing… my keyboard shortcuts! I’m a Linux guy at heart (I install cygwin on every Windows machine I own and/or use) so performing tasks quickly from the keyboard are a part of my computing lifestyle. For instance in Outlook I could always type ALT-T, Y to permanently delete items in my Recycle Bin. Not anymore! The new interfaces are very mouse-centric and while they look good they leave out the ole shortcuts that have become second nature to me.

Wait a minute, you say! You can still use keyboard shortcuts. That’s true. Now to perform the same task in Outlook I can simply type ALT-F, I, T, Y. That just rolls off the tongue (or fingers), doesn’t it? Maybe in the next version I’ll be able to type “P-L-E-A-S-E E-M-P-T-Y M-Y R-E-C-Y-C-L-E B-I-N, Y-E-S I A-M S-U-R-E, T-H-A-N-K Y-O-U”.

Hackety-Hack, Don’t Come Back

Posted on August 15, 2011 by Jonathan Franzone

Well, this has been a first for me. I was recently hacked on this very blog; or at least it was brought to my attention recently. I suppose it could have taken place a while ago. My hosting provider started sending me notices that my webspace account was generating large amounts of spam mail while I was away on vacation. So naturally by the time I got back home, they had shut down all of my websites. Of course, that was a good thing because they actually researched and found the offending scripts inside a WordPress theme that I had installed. Thus the reason that my blog is somewhat out of sorts now.

So a big thanks goes out to 1&1 Web Hosting for finding the problem and dealing with it in a reasonably quick fashion. Naturally I’ll be scrutinizing my WordPress themes a bit more closely from now on.

Windows Vista crcdisk.sys – System Won’t Boot

Posted on July 18, 2010 by Jonathan Franzone

I recently had a friend call me in need of computer repair assistance. I’ll save you the many hours of troubleshooting and simply list the fix here.

The Dreaded crcdisk.sys

I found this symptom of the problem by booting into Safe Mode and watching the drivers load. I noticed that it always hung for a long time on the crcdisk.sys file. Well, if you perform a search on Google for “windows vista crcdisk.sys” you will find a plethora of woes from computer users desperately trying to regain the functionality of their PC. There are also a plethora of fixes, advice and this worked for me posts. I tried many of these to no avail.

The Road To Recovery

The laptop I was working on was a Toshiba laptop and it had a system restore disk. Great! Sort of. Restoring the system to factory condition from the disk (after the owner had backed up their data of course) resulted in a system that was broken and still had the problem listed above. Hmmm.

Another operating system perhaps? I installed Windows XP from scratch. Worked great. I installed Windows Vista SP2 from scratch (another disk). Worked great. Re-tried the system restore from Toshiba. No good.

At this point I figured I was just going to install Vista from scratch. So I reinstalled Vista and downloaded the Toshiba drivers from their website. One by one I started installing the drivers. Until I got to the driver for a flash media card reader (front of laptop). Bam! It froze up during the install. So I rolled that change back using Windows System Restore and then continued with all of the other drivers. No problems. I tried the flash media driver one more time just to be sure, and sure enough it failed again. That’s good! Predictability is key in diagnosing computer problems.

Dump A MySQL Database To YAML Using PHP

Posted on July 16, 2010 by Jonathan Franzone

The Problem

I was recently working on a project that is built on WordPress / BuddyPress. I built up some content using the CMS features of WordPress in my development server and then I transfered the WordPress content to a beta server using the export/import functionality. That kind of stinks having to do that every time I want to push updates to my beta server. So I looked into using Doctrine to generate data fixtures which I could repeatedly run against the different database. Doctrine supports YAML files, which are extremely easy to edit by hand, so it seemed like a good idea.

So what’s the problem? Well, I didn’t currently have any of my data in YAML files. I didn’t want to had edit them or do some sort of copy and paste madness. So, I wrote a script in PHP to dump my data into a YAML file.
