Rejecting mail voting signatures without notifying voters before it’s too late will be not allowed going forward. From Ballot Access News:

On Sunday, October 16, U.S. District Court Judge Mark Walker held unconstitutional a Florida procedure for voters who vote by mail. Florida Democratic Party v Detzner, n.d., 4:16cv-607. Florida procedures permit no-excuse absentee mail balloting. However, the ballot of a voter who voted by mail, and whose signature on his or her outer envelope appears not to match his or her signature on the voter registration card, is not counted, and such voter is not informed until after the election is over.

The court order says that when a mail ballot is considered suspect because the signature on the envelope doesn’t match the signature, the voter must be notified before it is too late.

Nominated by President Obama for his job, U.S. District Court Judge Mark Walker made the ruling. Some background on him from the judge’s nomination announcement:
