Setting up a ASA 5510 cannot get SMTP to come in

Question

I have a ASA 5510 (ver 8.4) and I have been all over the support sites looking for what I am doing wrong. I have a sanitized cut n paste of the OBJECT, NAT, ACCESS-LIST and Packet Tracer output and it keeps failing on the NAT with a rpf-check. Once i get the SMTP flowing I have to open up HTTP and HTTPS to one of the servers also.
Any help greatly appreciated!!!

hi
Please use the public IP (5.29.79.12) in packet tracer command as a destination , not the private 172.17.1.49
