Fortimail IN HA Mode

Hi,

 Currently I am Using Fortimail 200D in HA (master-Slave).Its working fine. I have quarantine my spam email after checking legitimate email I release them. But issue is that when fortimail receive an email and relayed after receive I want resend this email due to user undelivered complain, I have no option to relay again this email manually.I have configured archiving on all email but when I want this email there is address of fortimail instead of original sender, Please suggest resend email when I want.

Thanks.
