It is done the way it is in order to not confuse people as the actual
address in the From: header is the list posting address, not Henrique
Fagundes address. I.e., if the "via clubenaval" were removed, the
message would be

From: Henrique Fagundes <clubenaval at groupos.aprendendolinux.com>

making it appear as if <clubenaval at groupos.aprendendolinux.com> was
Henrique Fagundes actual email address.

That said, you can remove the via listname by applying the following
change to Mailman/Handlers/CookHeaders.py

Also, later versions of Mailman (>=2.1.22) will translate "via" to "por"
for pt_BR. (The i18n was added in 2.1.21, but the pt_BR message catalog
wasn't updated until 2.1.22)
