MiaB + Mandrill + Mailchimp

I have my MiaB on main domain we use for our web app. We are using Mandrill to send email from our app. We also use Mailchimp to send newsletter to our users.

so, we’ve got two SPF and DKIM setup for the same domain:

mandrill._domainkey.camva.ir     TXT    v=DKIM1; k=rsa; ....
camva.ir  TXT   v=spf1 include:spf.mandrillapp ....


camva.ir  TXT   v=spf1 include:servers.mcs...
k1._domainkey.camva.ir    CNAME   dkim.mcsv.net

I have no SPF or DKIM for MiaB. there is no instruction on status check page. (we HAVE to use Rackspace DNS service. so using MiaB DNS is not possible).

Please advice me what to do. I probably can delete SPF for Mailchimp. Need to keep it for Mandrill (not sure it is required). what should I do?

Update: I understand SPF records can be merged. that’s solved. What about DKIM?

DKIM records are stored in subdomains that don’t affect each other, so you should be able to just follow Mandrill’s instructions without any problems.
