The mailin directory contains the Mailin library. The library handles parsing, the SMTP state machine and building responses.
The mailin-embedded directory contains an SMTP server that can be embedded into another program. This can be used to receive email within a program or to build a standalone email server.
The mailin-server directory contains an example standalone SMTP server that uses the mailin-embedded library.
The mxdns directory contains utilities for looking up IP addresses on DNS based blocklists and for doing reverse dns lookups.
The mime-event directory contains an event driven MIME parser. This parser can parse MIME messages line by line without allocating memory for the whole message.
