[wlug] Mailman/Pipermail Email Address Obsfucation

Hi, Does anybody her have experience in obsfucating email addresses in list archives to prevent spam harvesting using pipermail/mailman. The standard mailman privacy options only seem to apply to mailman configuration / list information pages not the archives which are generated by pipermail, and pipermail seems to be extinct. I would like all email addresses in the archives to appear as From: Matt Brown <matt(a)m...> rather than From: Matt Brown <matt(a)myrealdomain.com> Is anybody able to offer a solution to this problem? Regards -- Matt Brown matt(a)mattb.net.nz
