It is possible if your mail servers are listening on different ports but i suspect they are both using the SMTP port (port 25) which means that the pix would have no way of distinguishing which private IP to translate to.
It is not possible unless you change the SMTP port on the Mail Server, but that is not really a good idea. if ur ready to change the port on the mail server on one of the PC, then you can do PAT for a single public IP address to 2 different Private IP address.
eg. 220.127.116.11----->192.168.1.1 port 25
18.104.22.168----->192.168.1.2 port 26
this kind of rule you can very well create on the PIX firewall.
