[Mailman-Users] Changing values at header/footer

[Edgardo Sandoval]

Hello everibody,
This is my first list that I am setting and I wonder if I could add to my footer/header a small line like for example:
Message Ref.: #123456789   Date: 22/01/2015 17:10
I was searching to get a list of command in Python, like the original footer, but no good results:
%(real_name)s mailing list%(real_name)s@%(host_name)s%(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Thanks a lot from Argentina!Best regards,Edgardo
