That's the complicated version. ;-)

'Mail-Followup-To' can be generated by Gnus. You first must tell Gnus to
which mailing lists your are actually subscribed to, by setting the
"subscribed" group parameter (use 'G c' over the group and check
"Subscribed"). Then put

(setq message-subscribed-address-functions
      '(gnus-find-subscribed-addresses))

in your .gnus. This will set the variable 'message-subscribed-addresses'
(which you can also set directly, without using the group parameter).

Ah well, I'm not sure anymore that's less complicated, but this is what
the manual says. ;-) See:

(info "(message)Mailing Lists")

and the doc to 'subscribed' in

(info "(gnus)Group Parameters")

Regarding 'Mail-Copies-To': You can simply include it in your posting
styles, e.g. by putting

 (posting-style
  (Mail-Copies-To "never"))

in a group or topic. I'm not sure that's even needed when
mail-followup-to is set, but I include it anyway (many mail clients
ignore it, though).
