90 days is probably way more than most miners would expect.

I'd set this to 7 days for now, than work on getting this to the config

if deal.Proposal.StartEpoch > maxStartEpoch {
return false, fmt.Sprintf("deal start epoch is too far in the future: %s > %s", deal.Proposal.StartEpoch, maxStartEpoch), nil
}

if user != nil {
return user(ctx, deal)
}
