I think you missed the answer in the message you were responding to.
* ^Subject:.*is[  ]+out[  ]+of[  ]+the
should be the correct approach, with each of the []'s enclosing one
space and one tab character.  The [  ]+ expression means match one
or more (any number more) of the characters enclosed, so there has
to be one space and it won't matter if more or tabs are introduced
by the header wrap/indent.
