FastMail.com can send via a forwarding email address. You'll need to set up authentication at FastMail so it can authenticate to the forwarding service of course.

I don't use the forwarding service to send. I use it to forward incoming mail to FastMail, and in FastMail I just fake the sender address when sending e-mail.

Sadly your use-case is dying. Asymmetric mail flows are becoming harder and harder to support, as DKIM/DMARC alignment and SPF become stronger anti-spam signals, we're going to have to lock down on egress for domains which we don't have proof of control for.
