I need a VERY basic mailing list solution. I'm helping a friend move to a new web host and they currently have a mailing list setup that is incredibly simple. He sends an email to [email protected] and whatever HE sends gets forwarded to 200+ people, anything sent there by another email address is ignored. It is part of a custom control panel at that host though, not some downloadable software I'm aware of. I know this can be done by just CCing the message to all the people, but that would be a little more difficult. I've been looking at phplist but it looks like the only way to send is through the web interface, which is too feature rich for this person. Also, the users don't even need to subscribe, the admin just enters and removes them manually.
