We just upgraded to zimbra 6.0.1 and now adding
/^Sender: / IGNORE
to
/opt/zimbra/conf/postfix_header_checks.in
does not remove the "Sender:" in sent emails header anymore. So all recipients see the "On behalf of" again.
Worked pretty well for some months in 5.0...

Any idea on how to make this working again 6.0?

Thanks a lot!
