I am looking for a program that will allow me to send emails through as many yahoo accounts as I enter in to the program. This is a pretty common program and is easily available and cheap, BUT I have a yahoo server located in India that can be exploited to send countless emails into yahoo inboxes. I have the domain and port for this server.
I know this can be done, because I know someone that wrote this type of program, it works great, but they won't sell it.
I can also provide a screenshot of their program, plus email headers that are using the exploited server to email through, along with various info that the person that has the program divulged in some emails.
The UI can be simple, but I will need to be able to enter subject and message for emails, yahoo accounts and probably proxies.
If you are knowledgeable about emailing, protocols, smtps, proxies, etc, this should be pretty easy for you.
