[Users] I don't understand why the attached mail gets deleted as too old.

One of the few "good" solutions for dealing with missing Date: 
headers is to use the configuration option:
   always_add_missing_headers = yes
in Postfix main.cf. For malformed dates on incoming mail, that
suggests one should use some sort of filter that does something
like  "Date:" -> "X-Date-From-Moronic-Sofware:", then let Postfix
put in a new valid date. 

At least with *incoming* mail, the time of arrival shouldn't
be that different from what should be in the Date: header, so
it makes sense to handle it in the server, rather than in a
client.
