[Mailman-Users] Including sender's email address in footer of email

[herbmankr-mailman at yahoo.co.uk]

I'd like to try to set up the footer of the list I manage so that people can click a link if they want to reply to the sender only, rather than the whole list. Is there a way to do this? I read somewhere something about switching on personalisation, which I have done, but I've not got any further than that.

Thanks
