Hi,

I am using Haraka https://github.com/haraka/Haraka. After the upgrade to nodejs 6.7.0 TLS stopped working. Everytime a client started using TLS, haraka crashed with a segmentation fault. I am using a certificate from Let's Encrypt.

I don't know if it is an error in nodejs or in the way haraka is using it. In the former case, the following information from the core dump may be helpful:

Core was generated by `node /usr/bin/haraka -c /root/haraka-test'.
