Changed the Sendmail library to allow the separator between mail

headers to be specified as a parameter.  The documents say that it
should be "\r\n".  Some sendmail programs seem to violate the
specification and get confused.  In these cases the header separator
is just "\n".

This change allows the header separator to be set by the a
configuration parameter.
