 [This reasoning is invalid :-)]

 Upgrade to a current version of postfix, i.e. 1.1.2

 From HISTORY:

20000913
[...]
        Compatibility: don't insert Sender: header lines. Sendmail
        has not done so for at least 10 years, if it ever did.
        Problem reported by Brad Knowles. File: cleanup/cleanup_message.c.
 
 See also the comments in cleanup/cleanup_message.c (current version).
