Hi! Due to security reasons for browsing and mail marketing, I was checking for an app that, installed on my PC or on a VPS, could change easily IPs w/o have to manually enter into browser or mail sender settings to change proxy values. The idea is to mount a very simple home-made mail marketing system that could be located on my own PC (1-2K relays dayly) with installed Atomic/SendBlaster + HideMyAss (or every other similar software) setted to change IP every X minute and connect to godaddy/gmail/hostgator smtp accounts (see godaddy method) to send mails; also, the installation of this app on my PC should protect me from IP tracking, binding proxy with a VPN till their servers (e-security will be soon a big issue in the country where I live...). Would be very appreciated from experts any suggestion and if somebody knows this app or similar ones or if this schema simply does not provide the need protection (in a few words, it is crap...). Regards.
