Question Manage Email Mailing Lists

[parkerseal]

In Plesk on Windows, there doesn't appear to be a "Manage the list" option as described here (unless it's just my host!)
It would be useful to

1. Allow member-only or named senders - just the list administrator would be good enough
2. Allow moderated lists
3. Allow password-protected lists
4. If the list is switched off, any emails to it are forwarded to the list administrator

What I'm trying to achieve is to only allow specific people (maybe the list administrator) to send to the list, then any replies come back to the sender (or administrator) before maybe being forwarded to the whole list.

At present, it's just too insecure - the last thing I want is for a spammer or disgruntled member to be able to send to everyone on the list!
