mailgun has a free service level (first 10,000 emails a month) and you can add a filter to forward all emails to a domain to a specific email.
So if they do not match an existing route, they go to the catch all.

Hi Guys,
I've got a quick question, I'm in the process of moving a few sites I run over to a digital ocean / forge setup and need a way of making a catch all mail account for a few domains somewhere just to forward everything to one central email account. So i guess the service would need to be able to have mx records point towards it and then setup a catch all forwarder.
Does anybody know of such a service that is free to use or a cheap monthly cost?
