Important changes

• This release restricts the use of \n.\n as end-of-data delimiter to prevent inconsistency between email servers. This has been refered to as SMTP smuggling. The new default is to by default disallow, but auto-detect exception based on the first header line to prevent incompatibilities with old clients, while still preventing the SMTP smuggling behaviour.
