GMail/Hotmail Notifier (Python, Tk UI)


This was both an exercise after learning some Python and an application I needed as a simple replacement to my dear Digsby on Ubuntu.

It is an email notifier to automatically check mailbox every 60 seconds. In the case of GMail, it was no problem at all, just a couple of lines and I get the new "UnSeen" mail. But for Hotmail, it was a problem because POP3 protocol does not offer this feature. So if you use this script/application for Hotmail, notice that it will notify if any mail arrives after logging in, and notification will still be there until you log in again.

The application deals with one account at a time, but I could run several instances.

The script is not perfect but it did the job on both Ubuntu 10.10 and Windows 7 Professional :)




You can find a compiled version of the script (for linux) here : Download

for compiling the code, I used PyInstaller :
the process was as simple as that:
adly@ubuntu:~/Documents/pyinstaller-1.5$ python Configure.py 
adly@ubuntu:~/Documents/pyinstaller-1.5$ python Makespec.py --onefile /home/adly/Documents/mail_notifier.py
adly@ubuntu:~/Documents/pyinstaller-1.5$ python Build.py /home/adly/Documents/pyinstaller-1.5/mail_notifier/mail_notifier.spec

then the application was created in:
/home/adly/Documents/pyinstaller-1.5/mail_notifier/dist
