[Mailman-Users] privacy problem with mailman archives ?

[Rachel Willmer]

Looking at the public archives for the mailing list I've just created, it 
seems that there's a privacy problem.

The archives display the email addresses of the senders in a spam-readable 
format, which would make it very easy for a robot to pick off the names of 
anyone who's posted to my list.

Is there an option I've missed that obfusticates the email addresses of 
posters addresses in the archives, in the same way that the addresses in 
the list of subscribers can be spam-proofed ?

(using mailman v1.1)

thanks for any help
