Having a reverse DNS (PTR) record for the website as well sounds like a good idea anyway. If you want to use only one NIC for mail ports it should be possible to do so using TCP/IP filtering, but it might be some work to get it right.

Hello all,

 Got another question. I have one PC with 2 network cards, each configured with a different static IP.

1st card is for the Website. 2nd card i would like to be for the Mail server. How can i make Mercury32 use the 2nd card?

From MercuryS help:

IP Interface to use: If your computer supports multiple IP interfaces, you can use this field to tell MercuryS which interface it should select when listening for connections: enter the interface as a dotted IP address in the general form www.xxx.yyy.zzz. As an example, your system may have one IP address assigned to a dialup PPP connection, and another, different IP address assigned to a local Ethernet network - you would enter here the interface MercuryS should use. If you leave this field blank, MercuryS will listen on all available interfaces. Unless you are *very* sure of what you are doing, or have been instructed by an ISP or network administrator, you should leave this field blank. If you change the IP interface in this field, you must restart Mercury before the new interface number will be used. 

There are similar setting for the other server modules.

Ahh! Wright under my nose.

But what about the SMTP Client? How would i get it to use the IP i need? Do i add the IP of the NIC card to the "Address discovery and DNS access" in the Name servers: field?

Thanks,

Troy

Client modules won't bind to a specific network interface, it will be up to routing rules and TCP/IP filtering in Windows which one will be used. The MercuryE setting "Address discovery and DNS access" is just for address resolution and can in most cases be left blank.

Ok. Regarding the MercuryE, i have my TCP/IP setup on both NIC cards. But when i send a email i get back a failure which says the "IP number has no DNS record". The IP in the Returned Mail Failure is the IP for my website. This tells me that Mercury is using the wrong IP to send. Should i just add the website server IP to my Reverse PTR record?
