What's Changed

Most importantly, DMS is now protected by default against the security vulnerability called "SMTP smuggling". Moreover, we switched from raw netcat (nc) to swaks in our test suite - a change that is beneficial for upcoming changes and improvements to our test suite. Last but not least, the log path for Postgrey was corrected.
