Update to 0.42, provided by Todd Vierling in PR 21068:
2003-02-20 0.42
 - fixed a long-standing bug in dsbl handler - data received from
   the remote was not collected correctly.  Well, this one wasn't
   happened too frequently - I only seen it once, when a proxy
   delivered data from the target mailserver one byte at a time.
 - added yet another port, 1813 (socks5), as advanced (level2) port.
   SKK proxy listens here, but it is seen unfrequently.
2003-02-14 0.42b2
 - added proxylogger - receiving part of proxycheck, to be used
   from inetd and with -c chat.
2003-02-12 0.42b1
 - fixed a small bug in last wingate/telnet code changes (mostly
   cosmetic: "Resource temporarily unavailable" vs "Connection \ 
timed out").
 - added another telnet/wingate proxy variant, with a prompt
   "SpoonProxy>", which expects a command in form "host port"
   (instead of tn-wg/wingate which is of the form "host:port").
2003-02-04 0.42b
 - some code cleanups/changes: may break things, testing...
 - FTP proxy detection added, port 1183 only for now.  Interesting
   to experiment with M$ ftp servers ;)
 - fixed not finding advanced protocol if no ports are specified
   (e.g. -pwg: tried default protos:ports instead of wg:25,1181)
 - modified telnet/wingate proxy code to be a bit faster and to
   know which command to sent to a particular proxy.
