Google Apps Domain Create SPF Records For BIND or Djbdns

in Bind dns, UNIX last updated October 22, 2010

I work for a small business and outsourced our email hosting to Google. However, I noticed that spammers are using our From: First Last to send their spam messages. All bounced messages come to our catch only account. How do I stop this? How do I validate our domain using SPF? How do I configure a SPF for Google Apps domain using BIND 9 or djbdns?

I‘m trying to get data (AXFR query) from master tinydns server to secondary DNS server using tcpclient as follows:
tcpclient -v a.ns.example.com 53 axfr-get example.com example.com example.com.tmp

But I’m getting an error which read as follows:

>axfr-get: fatal: unable to parse AXFR results: protocol error

How do I fix this problem?
