Remember that NAT is not something that most IP-aware applications can deal with easily (cf. VPNs, et al.).&lt;/P&gt;&lt;P&gt;--Sandy&lt;/P&gt;</description><pubDate>Tue, 17 Aug 2004 19:01:04 GMT</pubDate><dc:creator>Sanford Whiteman</dc:creator></item><item><title>RE: Domains Literals Fail Behind NAT'd Firewall..

Why can't IpSwitch just fix imail to accept [0.0.0.0] as an alias for said domain.  &lt;/P&gt;</description><pubDate>Tue, 17 Aug 2004 08:55:05 GMT</pubDate><dc:creator>william.stillwell</dc:creator></item><item><title>RE: Domains Literals Fail Behind NAT'd Firewall..

At the network level, your mailserver should never need to route to its own public NAT address through the firewall, so the fact that you're "short-circuiting" the route by steering it to localhost should be okay.  &lt;/P&gt;&lt;P&gt;--Sandy &lt;/P&gt;</description><pubDate>Wed, 11 Aug 2004 00:47:29 GMT</pubDate><dc:creator>Sanford Whiteman</dc:creator></item><item><title>Domains Literals Fail Behind NAT'd Firewall..
