|
<div><p>This topic tells what you should do before you configure an e-mail
|
||
|
|
router.</p>
|
||
|
|
<p>Before you configure an e-mail router, consider the following aspects:</p>
|
||
|
|
<ul><li>The intermediate server does not have to be an iSeries™ server. The mail router only
|
||
|
|
requires a host table that contains all host servers to which it needs to
|
||
|
|
route e-mail. If an iSeries server is the mail router, it does not require
|
||
|
|
any particular system level.</li>
|
||
|
|
<li>You can set up only one intermediate server for routing between the source
|
||
|
|
and target server. You cannot nest mail routers.</li>
|
||
|
|
<li>Simple Mail Transfer Protocol (SMTP) must be able to get an IP address
|
||
|
|
for the mail router when it starts, either from the local host table or through
|
||
|
|
the Domain Name System (DNS) server. If SMTP cannot get an IP address for
|
||
|
|
the mail router, then SMTP runs without using a router.</li>
|
||
|
|
<li>The SMTP client firewall support uses the mail router
|
||
|
|
to forward e-mail that is destined for a host outside the local (protected)
|
||
|
|
domain. In order to deliver e-mail, the mail router must be a server that
|
||
|
|
is authorized to forward e-mail through the firewall. Also, mail recipients
|
||
|
|
whose domain is not on the iSeries server go through the router when you turn
|
||
|
|
on the SMTP firewall support. i5/OS™ V5R1 and later supports multiple
|
||
|
|
local domains. You can configure multiple domains that do not send mail through
|
||
|
|
the firewall.</li>
|
||
|
