Setup Ubuntu to send mail via a remote SMTP server

We will configure a server running Ubuntu to send all mail out to a remote email address via an SMTP server. This is a redo of these instructions..

Again, I just copied an instructional as here. Cant be bothered copying it here, but I did all those steps, except I commented out this line:

#smtp_tls_CAfile = /etc/postfix/cacert.pem

Because eh.

I looked at this log and got some useful info: /var/log/mail.log

SMTPS wrappermode (TCP port 465) requires setting "smtp_tls_wrappermode = yes", and "smtp_tls_security_level = encrypt" (or stronger) 

So I added those lines to my config file.
Then in testing I noticed that yay it actually sent the mail, although it bounced due to the ‘from address’ not being configured properly, so we create this file:
sudo nano /etc/postfix/generic with these contents:

username@hostname name@domain 
@hostname name@domain  
#use 'postmap /etc/postfix/generic' to hash this file 
#then 'service postfix restart'  

Where hostname is the hostname for the machine, and name@domain is the sender address, which usually needs to be valid with the SMTP server – although Google actually allows improper addresses. You could create different instances for different users, i.e one for root perhaps
Then add this line to the config:
smtp_generic_maps = hash:/etc/postfix/generic

Note that the hostname field needs to correspond as with
hostname –fqdn
and can be edited here
sudo nano /etc/hosts

I set the following in the
mydestination = localhost
meaning that only mail for localhost will be held on the machine

sudo postmap /etc/postfix/generic
sudo service postfix restart


Looking into HHO

I have heard about HHO a few years ago, and the last couple days I have been looking into this tech again. It appears the game of whack a mole is continuing by the petro dollar powers that be – many HHO site links are down and only visible in web archives. That being said, there seem to be no shortage of enthusiast inventors making their own devices and websites

HHO Technology

Heating with Hydrogen HHO or Hcat. This man does just that.

I have found a full kit for your car made by an auto shop “LaBella’s Auto Repair”, that even includes an OBD II computer to modify the ECU timing automatically. Seems super simple and I am considering buying one.. until…

HHO Installation Frequently Asked Questions

The above video seems very knowledgeable.. perhaps delving into this would require a much deeper dive than a simple plug in automatic OBD ECO controller..
Found an Australian 21 cell device..
This also looks worth watching:
