<p>I have a Mercury setup that I have used for years now.</p><p>It has been working great.</p><p>I just recently added a second network card to the same computer.</p><p>This 2nd NIC has a different IP, and gateway.</p><p>The first NIC is attached to a DSL line from one ISP, and the 2nd NIC is attached to a different Fiber line from a differnet ISP. </p><p>I am using this with 2 MX records - all pointing to the same instance of Mercury Mail.</p><p>Mercury is receiving mail just fine on both "lines" .</p><p>However, when Mercury sends it's initial "220 " helo on the 2nd NIC it looks like "220 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" instead of "220 domain.com"</p><p>everything otherwise seems to work.</p><p> </p>

<p>Are you sure you are looking directly at the Mercury/32 system when you do this?  This really looks like one of those strings where a router is messing with the reply from the system.</p><p> </p>
