not able to receive mail through pix 506e firewall

Hi I have pix 506e firewall, D-link ADSL dsl-502t and my IBM xseries 236 server. I have fix static live ip 59.181.103.220 which i have got from ISP. loyalindia.co.in is my domain, The MX record for it is mail.loyalindia.co.in which points to

59.181.103.220

My problem is i am not able to send mails ( with my mail server, Exchange server,loyalindia.co.in) through pix 506e but i am receiving mails from any server.

I have tried with (ADSL) natting and without natting but the problem is same. If i am removing the pix 506e and directly connecting the server to adsl i am able to receive and send mails properly

My network design is as fallows:- ADSL (WAN) 59.181.103.220 ADSL (LAN)59.181.103.221 Pix 506e (out) 59.181.103.222 Pix 506e (in) 192.168.1.1. My domain mail server loyalindia.co.in (Exchange server) ip

192.168.1.2
