====== Configuring Proxmox hosts (and other postfix installs) to send email via smarthost ======

Proxmox uses postfix as its MTA. To configure this to send email via smarthost run

  dpkg-reconfigure postfix

For general type we want Satellite

SMTP server - usual

Mailbox size - could use the suggested 51200000 here - should be more than big enough seeing as nothing should be ending up in the system mailbox anyway.

Once this is done, edit ''/etc/aliases''. It should look like:

  postmaster: root
  nobody: root
  hostmaster: root
  webmaster: root
  www: root

Add a line at the end:

  root: Your.Email@example.com

Regenerate the database with ''newaliases'' (or possibly ''postalias filename'' on other distributions)

Test with something like

  echo "test" | mail -s "test mail sent to root" root
