I've tried to have a list open, manually approving the messages of non-subscribers, but due to the amount of spam and virus, I can't handle the workload any more.

I want to allow posting of non-subscribers just if they use a form in my webpage (no direct emailing to the list address). It looks like that it isn't possible to automatically approve a message just if a header is present. Any tips on how to implement it?
