<br>&gt; anyone is interested it is the Regions bank building in<br>&gt; Indianapolis, IN.<br>&gt;<br>&gt; I am fairly confident that I can do this without help, but I<br>&gt; am taking the chance of posting here to make sure that I do
<br>&gt; not screw this up.<br>&gt;<br>&gt; As far as mail is concerned ....<br>&gt;<br>&gt; Mail is the only thing that I believe that will be affected<br>&gt; by the IP address change.<br>&gt; My Setup.<br>&gt;<br>&gt; Internet --&gt; Router --&gt; MailScanner Machine --&gt; Exchange server
<br>&gt;<br>&gt; Plan - Leave the MailScanner machine at the Regions Bankd<br>&gt; building but take the Exchange server to the new location.<br>&gt; All that I should have to do is use the MailScanner machine<br>&gt; to forward mail to the new IP Address shouldn't I?
<br>&gt;<br>&gt; 1. Change the mailertable<br>&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Current<br>&gt; <a href="http://woodmaclaw.com">woodmaclaw.com</a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;esmtp:[<a href="http://10.1.1.22">10.1.1.22</a>]<br>&gt; <a href="http://www.woodmaclaw.com">

<br>&gt; Billy Pumphrey<br><br>That should do it.&nbsp;&nbsp;I would limit connections to port 25 at the Exchange<br>location to incoming ONLY from the IP address of your MailScanner<br>machine.&nbsp;&nbsp;I would give myself ssh access to the MailScanner machine.
<br>Might not be a bad idea to move ssh to a port OTHER than 22.<br><br>Mike<br>--<br>MailScanner mailing list<br><a href="mailto:mailscanner@lists.mailscanner.info">mailscanner@lists.mailscanner.info</a><br><a href="http://lists.mailscanner.info/mailman/listinfo/mailscanner">
