Tell it to the IRS if your return isn’t postmarked by April 15.

Well, the IRS CAN receive your tax return days after April 15th if it postmarked on time, but even if you file late, chances are you are a procrastinator, and not committing fraud.

But with votes, the possibility for hijinks is infinitely greater. You have a congressional election, and, late on election night, you see you are 85 votes short. Now, with the proper advanced preparation, you can take 100 votes down to the post office on Wednesday and have them postmarked for election day. That way you know you only need to submit ballots for 100 centenarians, instead of maybe 1000 without knowing the tabulations. Is it easy to backdate postmarks? I don't know. Will postal employees be willing to be accomplices? I don't know. But, knowing what I know about human nature, such a scheme is far from impossible.

Not sure if that's the issue here. My understanding is that the issue before the SCOTUS is whether states can count ballots received after election day that are postmarked on or before election day.
