sendmail problem with crond on CentOS 8

[zhavranek]

rbme invoked from crond does not send e-mail. When invoked from interactive shell it works ok.

The problem is with the changed behavior of the shell built-in type statement. With PATH=/usr/bin:/bin (when invoked from crond) it will not find /usr/sbin/sendmail on CentOS 8 (it worked on CentOS 6).

Solution: set `SENDMAIL=/usr/sbin/sendmail' in rbme.conf or patch rbme file:

diff rbme.OLD rbme
164c164
< SENDMAIL="${SENDMAIL:=$(type -p sendmail)}"
---
> SENDMAIL="${SENDMAIL:=$(type -p sendmail || echo /usr/sbin/sendmail)}"
