The amount of mail without the required 'Message-ID' and 'Date' headers crossed my annoyance-threshold.
Here's a solution, using postfix:
`always_add_missing_headers = yes
`/^Date:[ ]*$/i STRIP`
This has two effects:
- if Date: header is blank, it will be stripped and logged that this is done
- missing required headers will be generated by postfix, including stripped ones
