        I've found another problem with the cfengine e-mailing process.
Basically, it doesn't allow for multiline SMTP responses.  Here's what my
mail server does:
------------------------------
$ telnet msa.sunet.com.au 25
Trying 203.166.102.37...
Connected to msa.sunet.com.au.
Escape character is '^]'.
220 msa.sunet.com.au ESMTP
helo test.example.local.
250-jupiter.sunet.com.au Ok.
250-AUTH LOGIN CRAM-MD5
250-AUTH=LOGIN CRAM-MD5 X-NETSCAPE-HAS-BUGS
250-XVERP=Courier
250-XEXDATA
250-XSECURITY=NONE,STARTTLS
250-PIPELINING
250-8BITMIME
250-SIZE
250 DSN
------------------------------

        As you can see, it's a multi-line response, as specified in RFC
821 Appendix E.  I quote:

------------------------------
The format for multiline replies requires that every line,
except the last, begin with the reply code, followed
immediately by a hyphen, "-" (also known as minus), followed by
text.  The last line will begin with the reply code, followed
immediately by <SP>, optionally some text, and <CRLF>.

For example:
        123-First line
        123-Second line
        123-234 text beginning with numbers
        123 The last line
------------------------------

        Below is my suggestion for modifying the Dialogue function, which
would probably fix this.  However, this is the first C I have written in 6
years or so, so it will need to be seriously double-checked.

------------------------------
int Dialogue(sd,s)

int sd;
char *s;

{ int sent,charcount = 0;
  char ch,linetype,f = '\0';

if ((s != NULL) && (*s != '\0'))
   {
   sent=send(sd,s,strlen(s),0);
   Debug("SENT(%d)->%s",sent,s);
   }
else
   {
   Debug("Nothing to send .. waiting for opening\n");
   }

while (recv(sd,&ch,1,0))
   {
   if (f == '\0')
      {
      f = ch;
      }
   if (charcount == 4)
      {
      linetype = ch;
      }

   Debug("%c",ch);

   if (ch == '\n' || ch == '\0')
      {
      charcount = 0;
      if (linetype == ' ')
         {
         break;
         }
      }
   charcount++;
   }

return ((f == '2') || (f == '3')); /* return code 200 or 300 from smtp*/
}
------------------------------
