Small (2 character) bug in smtp.c

[Eric Riehl <eriehl@email.unc.edu>]

In the file transports/smtp/smtp.c, near the end of the definition
of the getmxrr routine, there's a line that should read:

	  int l = ranny(len-1);

instead of

	  int l = ranny(len);

That's all.

Thanks,
  Eric Riehl


Note: IMHO, you might also want to put the line:

	mx [0] . host = NULL

at the beginning of the function instead of makeing the calling
routing always do so.
