From addresses should also be rewritten for domains with a DMARC policy of "quarantine"

[raboof]

DMARC has three policies: 'none', 'quarantine' or 'reject'.

When ezmlm processes an email, it checks whether the policy is 'reject', and in that case rewrites the 'From'.

It might be good if it also (provided an option to) rewrite the From for domains with a policy of 'quarantine', to prevent those emails to end up in spam?
