Some server send email without Date header, and Thunderbird doesn't recognize the date.So, I want to use following settings and add Date header.
local_header_rewrite_clients = permit_inet_interfaces, ermit_sasl_authenticated
always_add_missing_headers = yes
But postfix.org says this may break DKIM signatures. Is there a way to add Date headers withoud break DKIM signatures ? (My mail server using DKIM.)
Example of no Date header mail :
