Is second.com a registered domain name ?

Looking at the MX record, your domain name is pointing to a private ip address ?

> second.com
Server:  mygateway1.ar7
Address:  192.168.1.1

Is that your registered domain name? if yes then private ip address are not routable to the public network.

Have you added the second domain to recipient policy in ESM? You cannot just add a domain to the user accounts - Exchange will not accept the email unless it is in recipient policy.
