oobgen to/from the wrong way around?

[tuck1s]

Here's an example run

2018/05/15 18:46:28 Got domain [email.thetucks.com] from Return-Path
2018/05/15 18:46:28 Got MX [smtp.sparkpostmail.com.] for [email.thetucks.com]
2018/05/15 18:46:28 Would send OOB from [steve@email.thetucks.com] to [msprvs1=17673tNX0QAs1=bounces-1026@email.thetucks.com] via [smtp.sparkpostmail.com.:25]
2018/05/15 18:46:28

The from/to seems to be oriented with the input file, not the oobgen output, which is
