05. Run the following commands in the terminal
send a basic test email
echo "Test email from Proxmox: $(hostname)" | /usr/bin/proxmox-mail-forward
output the mail log
cat /var/log/mail.log
06. Notice the relay is the domain (i12bretro.local) from the Email from address setting

Advanced Configuration via CLI
--------------------------------------------------------------------
To make more advanced configuration changes, like using a gmail account, you need to edit the postfix settings via command line
01. Back in the Proxmox web shell, run the following commands in the terminal
install libsasl
apt install libsasl2-modules -y
edit the postfix config
nano /etc/postfix/main.cf
02. Press CTRL+W and search for mydestination
03. Comment out mydestination by adding a # to the beginning of the line
04. Press CTRL+W and search for relayhost
05. Comment out relayhost by adding a # to the beginning of the line
06. Update or add the following configuration
relayhost = smtp.gmail.com:587
smtp_use_tls = yes
smtp_sasl_auth_enable = yes
smtp_sasl_security_options =
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_tls_CAfile = /etc/ssl/certs/Entrust_Root_Certification_Authority.pem
07. Press CTRL+O, Enter, CTRL+X to write the changes
08. Continue with the following commands in the terminal
create /etc/postfix/sasl_passwd
nano /etc/postfix/sasl_passwd
09. Add a line to configure gmail authentication
smtp.gmail.com:587 ≪%youraccount%≫@gmail.com:≪%yourpassword%≫
10. Press CTRL+O, Enter, CTRL+X to write the changes

update postfix lookup tables
postmap hash:/etc/postfix/sasl_passwd
limit access to sasl_passwd to only root

restart postfix service
systemctl restart postfix
test from postfix directly
echo "Test email from Proxmox: $(hostname)" | mail -s "Proxmox Testing" ≪%youraccount%≫@gmail.com
