Configuring Outbound and Inbound SMTP mails with SUN Java messaging system

Question

hi all,
i am new to Solaris i have deployed SUN java comuunication Suite. How do i configure my messaging server to send outgoing mails through existing gateway and recieve inbound mails from the same gateway?
Currently my server is connected to the internet directly i am able to send a mail to an external domain for example gmail. Can anyone help me out in understanding the default functioning of external mail routing and how do i point to a gateway?
Thanks,
Zafrul

To configure outgoing emails to be relayed through a gateway, you need to modify the <msg_base>/config/imta.cnf MTA configuration file and add "deamon <gateway hostname>" to your tcp_local channel configuration e.g.
! tcp_local
tcp_local smtp mx single_sys remotehost inner switchchannel identnonenumeric subdirs 20 maxjobs 7
pool SMTP_POOL maytlsserver maysaslserver saslswitchchannel tcp_auth missingrecipientpolicy 0
loopcheck daemon mygateway.com
tcp-daemonTo allow the gateway system to send emails to your host unconditionally, modify the <msg_base>/config/mappings MTA configuration fail and add the gateway's IP address to the INTERNAL_IP mapping table e.g. (where the gateway has an IP of 1.2.3.4 and your system has an IP of 192.168.1.20)
INTERNAL_IP
  $(192.168.1.20/24)  $Y
  $(1.2.3.4/32)            $Y
  127.0.0.1  $Y
  *  $NOnce you have done this you will need to rebuild the MTA configuration cache and restart the MTA processes.
<msg_base>/sbin/imsimta cnbuild
<msg_base>/sbin/imsimta restart

Can anyone help me out in understanding the default functioning of external mail routing and how do i point to a gateway?For the understanding, you will need to read-up the manuals. Messaging server is a flexible and powerful product for sending/processing emails, but with that flexibility comes complexity. I suggest you start by reading the Messaging Server Administration Guide:
