Thank you for replying Tom
I was not aware that SendMail and postfix.sendmail were two different
things. Thanks for the tip.
I removed all of SendMail packages and made sure postfix and sendmail are
installed.
Postfix is already configured to be able to send mail.
I also noticed that fail2ban-mail package was not installed, so i installed
that too to see if the service would fail when "mta=mail".
Fortunately the fail2ban service restarted properly with mta=mail and i was
able to receive emails.
So that was the issue fail2ban-mail was not installed
Thanks!
