Milter-greylist

Geez, I can't keep milter-greylist running for more then ten minutes
this morning.  It starts into the "Milter read(greylist): timeout before
data read" almost at once after I start it.
 
I put that code in, here's what I got:
Oct 28 08:10:31 hns1 milter-greylist: [ID 799890 mail.info] dumpfd = 15
Oct 28 08:15:39 hns1 milter-greylist: [ID 799890 mail.info] dumpfd = 348
Oct 28 08:15:39 hns1 milter-greylist: [ID 180808 mail.error] dumpfd =
348, dump = 0, errno = 0
Oct 28 08:15:39 hns1 milter-greylist: [ID 180808 mail.error] dumpfd =

Here is the code that causes this failure:

        if ((dump = fdopen(dumpfd, "w")) == NULL) {
                syslog(LOG_ERR, "cannot write dumpfile \"%s\": %s",
                    newdumpfile, strerror(errno));
                exit(EX_OSERR);
        } 

So your OS was not able to open that file, but doesn't tell us why
(errno says no error occured). You can add this before the syslog call:

                syslog(LOG_ERR, "dumpfd = %d, dump = %p, errno = %d\n",
                    dumpfd, dump, errno); 

to check that it's not strerror() that is misbehaving.

According to the X/Open spec:
http://www.opengroup.org/onlinepubs/007908799/xsh/fdopen.html
"Upon successful completion, fdopen() returns a pointer to a stream.
Otherwise, a null pointer is returned and errno is set to indicate the
error. "

So I'd say fdopen() does not behaves as expected. Is this a bug in your
OS?
