Certainly given sufficient hooks in the MTA, you might be able to  
make various decisions about the acceptability of a message at SMTP  
time, although it depends on where in the SMTP dialog you want to  
hook in.  There's no magic in Mailman that would prevent that -- a  
bit of Python would do the trick.

It's not something I'd personally develop because by definition,  
integration is highly MTA dependent, but I'd accept contributions and  
would be willing to improve the Mailman infrastructure to make things  
easier (e.g. see some of the re-org I'm doing in the 2.2 branch to  
move functionality out of scripts and into the Mailman package so  
that 3rd party Python code can get to it).
