Simple Mailer is a GUI Application written in python and wxpython as GUI toolkit. It's like a mailer program or simple smtp client that can be used not only to send emails with file attachment but also to do some jobs:
- Authentication test
- Recipient Address Check
- Sender Check
It supports SASL and TLS security and of coure some regex to check the validity of the email address.
Those features available on version 1.1
Another thing it has an encrypted config file which containts your signature and your email accounts. So you don't need memorize all email passwords only need one masterkey to read the config.
Python version: 2.7
This is the looking of the final application (click on the image below to show the youtube video).
Personally this is my first GUI programming with wxpython. I am prefer wxpython than tkinter due to native look-and-feel :).
You should use python 2.7 and install some dependencies in order wxpython to work.
Debian or Ubuntu.
apt-get install python-wxglade pyqt4-dev-tools python-qt4-doc
Windows which has already installed python2.7.
pip install -U wxPython
The application name is simpleMailer.py. You can execute it by entering command
python simpleMailer.py
Images such as email icon, exit menu icon, etc are embedded into script myImages.py using script
img2py.py (Linux) or application img2py (Windows).
For Linux
python /usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/tools/img2py.py -i icons/email-icon.png myImages.py
For Windows, first make sure Python27 already in PATH
PATH=C:\Windows\system32;C:\Windows;...;C:\Python27;C:\Python27\Scripts
img2py -i icons\email-icon.png myImages.py
For adding a new icon in Linux
python /usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/tools/img2py.py -ai icons/exit-item.png myImages.py
Or in Windows
img2py -ai icons\exit-item.png myImages.py
All icons are downloaded from this site
Install pyinstaller using pip
pip install pyinstaller
Then create one file application exe with an icon python-icon.ico
pyinstaller -F -w -i python-icon.ico simpleMailer.py
If the compilation is success it will create some directories
Go to dist directory. The stand alone application will have a name simpleMailer.exe and an icon.
You can execute this application on Linux too using wine ;).
This executed on Ubuntu 22.04.
I'm developing this GUI Application from the very start until the final stages. From the easiest stage to the most difficult one.
This is my first application. It's very simple. Email is sent by unsecure link. This email is not encrypted, its contents are transmitted as plain, readable text. This leaves the information vulnerable to interception by malicious actors, such as hackers or even your internet service provide. Test the application only on your LAN.
There's a method to check all entries must be filled before send the email or pressing the OK button.
Add features
- Regex to check the email validity
- An icon which shown at the top left of the application
- Version 1.0
Add features
- Authentication test
- Recipient Address Check
- Sender Check
- PLAIN without authentication using port 25
- PLAIN with authentication using port 587
- TLS using port 587
- SSL using port 465
- Version 1.1
Add features
- Use file config.ini to save the accounts
- Signature
- Email address
- Password
- SMTP Host
- Use control on menu combobox to select the account
- Support file attachment
- Version 1.2
You must edit the file config.ini using text editor such as Notepad or Vim.
On this stage, the entries passkey, signature and password onconfig.ini is encrypted using Crypto.Hash.SHA256. You can create and edit the config file in the application itself. The password hashed is supported both in Linux and windows.
Coming soon.
On this stage, the file config.ini renamed to config.data and is encrypted
with aesPBKDF2. You can create and edit the config file in the application itself.
This encrypion module is supported both in Linux and windows.
Coming soon.
