If we are to allow voting by mail/absentee voting it should be a "meet in the middle" process:
Mail out the ballots only by those requesting one, but someone (either the voter themselves or a designated delivery person) has to hand deliver the ballot to their precinct on election day. This would flush out the mules and ensure your ballot doesn't get thrown away and replaced with a Democrat pre-filled ballot.
