Yes, but no. Previously mail was postmarked locally because it was processed locally. Now they have gotten rid of local processing and it all gets first processed at a regional hub. However you could always have it postmarked at the desk to be absolutely sure it happens on the day you mailed it.
So you can still ask for a manual postmark at the office you drop it off at and it will override whatever date it gets regionally processed.
I thought this change is that the date is marked by a regional processing machine, instead of at the local post office?

Hope this still abides come November…
