`Auto-Submitted` is defined in the rfc 5436 [1] and describes how
an automatic response (f.e. ooo replies, etc.) should behave on the
emails. When using `Auto-Submitted: auto-generated` (or any value
other than `none`) automatic replies won't be triggered.

Note: this is already merged in `proxmox_sys::mail::sendmail`,
      which is used by pbs and pve. This is aimed at pmg, which
      still uses the perl implementation and for keeping the email
      behavior consistent through all products.
