--TODO--

   +	Consider adding SASL and man-in-middle support for AUTH
	DIGEST-MD5 and possibly other mechanisms.
	
   +	Consider adding man-in-middle support for STARTTLS.

--0.5.14--

  !!	License 1.4 which provides additional details with regards to
  	possible license controls used, the possibility of "phone
  	home code" and its general contents, and related privacy
  	statement.

--0.5--

   !	Unix: Corrections for gcc -Wall warnings and errors.

   !	unix: Fix the dropping of privileges to be more precise with
	respect to the saved IDs, which can be problematic on some
	OSes which handle setuid() with slightly different semantics.
	The following was an interesting discussion of the issues:
   	
   	http://www.cs.berkeley.edu/~daw/papers/setuid-usenix02.pdf
   
   !	Added #ifdef wrappers for some of the more esoteric functions.

   +	Added process fork() support when there is no POSIX threads.
   	Minix 3.1.2 doesn't support threads yet. 
   	
--0.4--

   !	unix: Fixed binding to port 25 when -u option is used. 

   !	Make sure to set the user's supplemental groups or release
   	those of root.
   
   !	socketReadLine() handles the timeouts on non-blocking sockets,
	so socketHasInput() in smtpGetResponse() is not required.
	
   !	Guard against buffer overflow when appending CRLF to the
	client input buffer and single server response.
   
--0.3--

   +	Requires LibSnert 1.57.

   +	fixed use of setlogmask() for Unix syslog() API.
   
   +	roundhouse() now disables socket linger and Nagle algorithm to
	improve throughput on high volume mail servers.
   	
  !!	socketAccept() failed to return NULL in the event of an
	accept() error and would return a pointer to freed memory.
   	
--0.2--

   +	Requires LibSnert 1.56.

   +	Moved socket.[ch] into LibSnert.
   
   +	Moved clamstream.c into LibSnert tools.

   !	Renamed Socket type to Socket2 with move of socket.[ch].
   
   +	Added support for AUTH LOGIN used by Outlook Express.
   
   -	Dropped AUTH DIGEST-MD5 from the EHLO response. Its not
	possible to multiplex the different SMTP responses from
	multple servers.
	
   !	When -a is used then all log output goes to standard error
	instead of syslog().

--0.1--

   +	Requires LibSnert 1.52.
