In light of the CERT VU#800113 announcement, DNS-OARC has created a special DNS name and server that you can query to determine if your resolver is at risk.
Usage:
dig @4.2.2.3 +short porttest.dns-oarc.net TXT
Replace 4.2.2.3 with your resolvers address. The result will either return FAIR, GOOD or POOR based on the observed deviation of the source ports.
Full details of DNS-OARC test can be seen here.

Quote:
An attacker with the ability to conduct a successful cache poisoning attack can cause a nameserver’s clients to contact the incorrect, and possibly malicious, hosts for particular services. Consequently, web traffic, email, and other important network data can be redirected to systems under the attacker’s control.
At least 30 vendors appear to be known vulnerable. This is a significant number. Start contacting your vendors!

“SendMail 1998 – Sendmail was key to the e-mail revolution because it was how everyone got up and running with e-mail communications over the Internet. Eric Allman wrote the original version of this open source mail-transfer agent while he was at the University of California at Berkeley in 1979. He stopped development on it in 1982, however, and didn’t revisit it until 1990. In 1998 he founded SendMail to sell the software’s first commercial version, the SendMail switch.”
