I can't tell you how to change the wrapper's expected group in a Debian
package. That's a Debian question, not a Mailman question.

But I can tell you that Postfix will pipe to Mailman using the
owner:group of the aliases* files in which it finds the Mailman
aliases, so you may be able to fix this on the Postfix side by
changing that owner:group or by putting Mailman's aliases in separate
files with appropriate owner:group.
