Gonna need a source on that one, chief.
The example I always use is when a college coach tells an athlete they've been accepted to a college before the admissions committee formerly approves them, and they actually get rejected. This happens dozens of times per year, and the reason you never see any lawsuits about it is that the colleges just let them in to avoid the bad publicity.
If the athlete turned up waving a _spoofed_ email and they let them in then that would be a more appropriate example.
Fair, I was just making the point about the validity of email agreements in general.
But let's say Harvard let others send email that appeared to come from their domain (by not having SPF enabled) and some kid withdrew all their other college applications because one of their friends was playing a prank on them or whatever, almost certainly the college would either let them in or else settle and pay damages. No way in hell they would want that going to trial even if they thought they could win.
Email domain spoofing is super easy.
