A few days back, I worked on an Email dispatcher command-line application which had capabilities of zipping up reports and emailing the reports to the clients at an astonishingly fast speed of hundreds of reports per min (assuming each report has 150,000 records with min of 6 columns).

Here, I am implementing a similar application but with a smaller + different set of requirement which are as follows:

1) Perform robust regular-expression based pattern matching & error reporting capability

2) Handle passwords efficiently from command-line (will improve the method later)

3) Use efficient Object-oriented Design & Modular code

4) Program is specific to Gmail (smtp address and port number). One can change this set of values to handle other major email providers.
