Worse, as $MAIL_NOT_INSTALLED is always "0" or "1", -z always return false...

Subject: [PATCH] Fix mail_tests for systems with mail installed

`-z' tests for a string length of zero, not for a zero value, causing the
test always to return false.
Initialize $MAIL_NOT_INSTALLED to an empty string instead of a numerical
zero to fix this.
