Consider supporting local sendmail rather than SMTP for email

Thanks for taking on a modernisation of this tool!

I looked into using it, but I'm not too excited about duplicating my SMTP credentials in both the TrueNAS config and the YAML config for autobackup. It would probably not be a particularly big change to your code to take the formatted message and pipe it into a /usr/sbin/sendmail subprocess (somewhat like how the original version just pipes to mail). Have you considered that? Would you be open to a patch?

Hi @0xabu
Thanks for the interest. I have tried to use the linux mail process from the original version but gave up trying to get it to work. I really don't know enough python or bash and ChatGPT was no help either ;-)
If you know how to, I would welcome a PR. Ideally it would support both options.

I have looked in my notes and have found the reason why sendmail did not work. It was possible to use sendmail as root from within a python script, but it was not possible from inside a venv, from python or even from bash. If you activate the venv and execute (venv) # echo "script started" | mail -s "test" "root" it will return an error. If you know how to get it to work, please let me know.
