Well no, as mimedefang is not talking to the client.  If you are using 
socketmaps with mimedefang you can tell sendmail to greet pause the 
connected client.

On the other hand I seem to be the only one using this approach, and 
although it looks nice and all, it's damn slow (as David pointed out in 
an earlier mail)

If an "example" is wanted I think I can make one for you, keep in mind 
socketmap is slow.
