no static (inside,outside) tcp interface smtp S1Server smtp netmask 255.255.255.255<br />

Hi, <br />
<br />
Company has two servers, one is email server and one is web server, external only one true IP.<br />
<br />
internal IP as follows:<br />
email server 192.168.1.1 (S1)<br />
we server 192.168.1.2 &nbsp;(S2)<br />
<br />
Later, we are going to migrate the email system from S1 to S2, I am not familiar ASA 5505 command, how can we change the NAT settings so that all emails to S1 will be redirected to S2.<br />
<br />
I dumped the startup config and it has following config data<br />
<br />
nat (inside) 0 access-list outside_1_cryptomap<br />
nat (inside) 1 0.0.0.0 0.0.0.0<br />
