SMTP/DSN support in Archiveopteryx

The DSN extension helps with error reporting: A client can say which kinds of error/success reports it wants regarding a message, and it can specify an ID which can help correlate the reports and the message. Archiveopteryx implements it fully and correctly, except that the length of a bounce message is limited.

It is required for Lemonade compliance.
