Gnus has never done this for me, although the message that I am
replying to here is pretty strong evidence that it does happen. :-)

Well, I don't do anything special...

(setq gnus-posting-styles
      '((".*" 
	 (name "Steve Youngs")
	 (address "steve@this.address"))
        ("^nnml:group.to.use.diff.address"
         (address "steve@somewhere.else"))))

In that example, sending mail from any group _except_
`nnml:group.to.use.diff.address' will have a from header:

  From: Steve Youngs <steve@this.address>

Messages from `nnml:group.to.use.diff.address' will have:

  From: Steve Youngs <steve@somewhere.else>
