Notify mail update (#2293)

Browse Source 
* feat: disable e-mail validation if MAIL_NOVALIDATE is set

* fix: expose _MAIL_BIN variable

* fix: call _mail_body and _mail_cmnd directly to make sure that all used variables are exposed

* fix: update notify/mail.sh

Co-Authored-By: Matej Mihevc <zuexo@users.noreply.github.com>

* fix: remove useless echo, quote eval
