X-Authentication error in headers of email - how to fix?

[Jody Cleveland]

Hello,

I've noticed, in the header of emails I receive, there is an error
message:

X-Authentication-Warning: mailman.winnefox.org: postfix set sender to
postmaster using -f

Any ideas on what it mean, or how to fix it?

I'm running MailScanner 4.42.9-1 with SpamAssassin 3.0.4 on a redhat 3.0
AS server.
