AddThis.com automated tool

Purpose: To notify subscribed users of website updates. Preferred Lang: C++, Python Can be done in: PHP, Python, VB.NET, OS: Windows/Linux, or it can be multi-platformed for both functionality on Windows/Linux Project Description: I will need a multi-threaded program, that will go from the start of an e-mail list to the end, and let them know we have updated our website via our website's [login to view URL] widget, these can be multiple websites, so we would need a way to configure the email list, the number of connections we will need, and to use our company's intricate IP network. We have many socks proxies that we use within our company's LAN (Local-Area-Network) and only these are authorized to post to our website with our website permissions, so we would need a way to specify which IP:Port to use to post, and to define if it's SOCKS 4/5/HTTP/S. The three main points would be, website URL(s) to post to, number of threads specified by the user, and location of the email of subscribers to send website updates to. The process would need the following:  Number of threads (socket connections) to use, speficied by the user.  Sender from's, these need to be configured also as a list supplied by the user.  Recipients, these must be configured and supplied by the user.  Proxies to use, these must be grabbed from our company's URL in text format: It will need to be grabbed from location such as: [login to view URL] and the format looks like this: [login to view URL] # SOCKS5 [login to view URL] # SOCKS5 [login to view URL] # SOCKS5 [login to view URL] # SOCKS5 - Errors should be logged, and handled properly. If we catch an error from a certain IP, we should temporarily nullify the IP and not use it for a period of 24 hours. This means we must catch errors, log the bad IP that is not sending updates properly to our subscribers and we must use a new one. - The program should be able to handle lists of 10,000 users or more. - Interface can be driven via web or command line, or regular interface for windows, which allows the user to configure the tool properly.
