test(1) is supposed to be portable

          if test "${InMail}" = 'gene'

The classic way is to use only gestures which are supported by the
Bourne shell and to avoid certain peculiarities of some shells.
In ./configure scripts of source packages one can see gestures
like

          if test "x${InMail}" = xgene

which avoids to compare empty variable content.
