[Mailman-Users] Post number in subject line

[Soben]

Hello all,

Is there anyone know how to show the post number in subject line? This number 
will be increased every time the member post something to the list. I have 
tried to search through Mailman's settings but seem no luck.

Thank you in advanced

Soben
