I suggest to unset the local_date_header configuration option.

From the manual:

        3.171. local_date_header

        Type: boolean
        Default: yes

        If set, the date in the Date header of emails that you send will be in 
your
        local timezone. If unset a UTC date will be used instead to avoid 
leaking
        information about your current location.

Best regards
Uwe
