Changes since version 1.0:

The anonserv shell script has been replaced by doalias.c
This program provides more informative acknowledgement messages,
and a way to supress acknowledgements (add a header Ack: no)

Added a sendused address feature to get a list of used nyms.

Fixed the bug which caused it to parse lines in the message body as if they
were headers (was causing some passwords and reply blocks to get clobbered).

Set the proper umask.

Fixed several bounds-checking problems (let me know if you find any more).
