I believe the SMTP service will simply use the first IP address in the binding order to make outbound connections.

Try shifting the binding order and see if that helps.

Yes,You can use/blind other IP in local SMTP to send mails.

Go to IIS.
Select default SMTP virtual server properties.
Select IP address to which you want to use.
The go the Access TAB
Then select relay restration option
ADD IP address.

Warm Regards,

Hi Vipin,

My IP addresses are *.81, *.84, *.85

My server uses .81 for outgoing connections but I want vSMTP to use .85 for outgoing connections.

I tried your idea of adding a relay restriction option, I selected .85, and I granted relay to .85

However, when emails get sent they still have .81 in, so it seems that the vSMTP is still using .81 for outgoing connections.

Thanks for the help,
Marc.

Hi Dave,

I changed the IP order in the NIC but the box (and vSMTP) still seems to use .81 for outgoing connections....I thought at first that might have done it but it hasn't.

Hi Vipin,

That's what I tried to do, setup a relay for .85, but the when email's get sent they still have .81 in the header.

To confirm, I selected .85 on the 'General' tab, then on the 'Access' tab -> relay restrictions -> 'only the list below' -> granted .85

Thanks,
Marc

How did you change the order of the IP addresses?

I believe SMTP will use the one that shows up as the first on the list.

Did you restart the service after making the change?

I changed the order in the NIC settings under "ip addresses" ...turns out that my server provider said I can only use on of my three IP for outgoing connections anways, so getting vSMTP to use a different IP is a moot point now.

Thanks for helping guys, I'll split the points.
