you simply configure it to have wananchi.com in relay_domains, that
should be it.

if you feel like, you can set up a different retry rule for that
domain (so, say, mails going to other domains will bounce back in 4d
if they can't be delivered, mails going to wananchi.com will wait a
week before doing so).
