Sending mail from Betty Blocks apps is done through Mandrill (mandrillapp.com). Mandrill requires that the sender-domain is verified before it can be used to send mail. If your domain isn't verified yet, you'll receive `error: unsigned` when executing your mail event. Here's how you can tackle this.
The following steps can be followed to get verified:
v=spf1 include:spf.mandrillapp.com ?all
If a SPF-record already exists, add:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;
If the method above still doesn't suffice, and you want to send mails using your own SMTP server, that's possible too! Although not available through the interface, we can do this for you. Contact us to have it set up.
