I'm confident that it does - nobody else, including some very pernickety big mailhosts, complained, and while I'm not doing it now, for a while I had a gmail address on the list so I could check DKIM and SPF as seen by gmail, which were always correct. (No, I haven't "upgraded" any of my mail software recently, either!)
