When using 
	--without-imap
or equivalently
	--with-imap=no

the configure script aborts with the message:

checking for IMAP support... 
configure: error: could not find imap library!


I believe that the if/then/else logic at the and of
this part of configure is broken slightly. I think the
following code fragement should just be eliminated:

  else

	    { echo "configure: error: could not find imap library!" 1>&2; exit 1; }
  fi

P.S.: Compiling --with-imap  works just fine.
