What I'm looking for is only simply described as a mailing list hosting script.
I want to have the ability to host a mailing list server, where members could register to use an extensive mailing list manager. This script must have the ability to host over a million members and emails, that the members have in their mailing list database.
This must be a very extensive mailing list manager, with all the fixings. Preferebly have all of the features that PoMMo mailing list has!
I don't want a premade script, so if you are bidding, this must be an original script, by bidding you agree that the script has not been copied from somewhere else. If it is, you will be liable for any legal issues that I may encounter, if I encounter copyright issues in the future.
