Changing the sender list on Full Frame Systems requires a DKIM and SPF record to be added to the DNS settings for your website. Below you will find the necessary instructions to accomplish this as given to us by our email sending service. Once this has been completed please contact us so that we can proceed with the verification process on our end.
DKIM
DKIM is a DNS-based email authentication mechanism that helps Mandrill more effectively send mail on your behalf by allowing receivers to verify that we have permission to send your email. To enable DKIM, create a TXT record for mandrill._domainkey.yourdomain.com (just replace yourdomain.com with the domain you're setting up) with the following value:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;
Some DNS providers require that semicolons be escaped. If your provider requires escaping, use this value instead:
v=DKIM1\; k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB\;
SPF
SPF is another DNS-based email authentication mechanism. If you don't yet have an SPF record, you'll want to add one for your domain. At a minimum, the value should be the following if you're only sending mail through Mandrill for that domain:
v=spf1 include:spf.mandrillapp.com ?all
If you already have a TXT record with SPF information, you'll need to add Mandrill's servers to that record by adding include:spf.mandrillapp.com in the record (before the last operator, which is usually ?all, ~all, or -all).
