I have an SPF problem. Hosting provider told me everything is right on their end

I managed to send test emails twice using dreamhost’s SMTP. But after that everything else go to the spam folder. With dreamhost’s delivery subsystem. And I am getting this error: [BFD] Sender prohibited by SPF (in reply to end of DATA command)

This is the SPF record I added as TXT:
v=spf1 a mx include:netblocks.dreamhost.com include:relay.mailchannels.net include:helpscoutemail.com include:sendgrid.net include:spf.mailpoet.com include:spf.sendingservice.net include:spf.messagingengine.com ~all

What am I missing? Dreamhost asked me to contact Mailpoet, something about making sure the IP can send mails. Or something. And that mailpoet would know what to do.
