No, the postfix header is correct. Look as the headers of
this message. The time format in the headers is:
HH:MM:SS [local offset from GMT] [timezone]

The offset and timezone are optional, if the timezone is
supplied, the offset. If no offset is provided, GMT is assumed.

But anyway, you're looking in the wrong place. The date/time
in your mail client is provided by the Date: header. Let's
see what that says...

Ah, there's the problem. No offset is provided, so **YOUR
MAIL CLIENT** assumes it's GMT and applies **YOUR PC'S**
offset, which is -400.

If you want to fix this, fix whatever is sending the mail.
Either set its time zone so it can provide an offset, or set
it to GMT rather than local time.
