<div><p>You can learn the procedures for using firewalls, restricting relays

|
and connections, and filtering out viruses.</p>
|
||
|
|
<p>It is important to promote a secure environment in your iSeries™ Simple
|
||
|
|
Mail Transfer Protocol (SMTP) server. You must protect your SMTP server and
|
||
|
|
your users from internal and external hindrances.</p>

<li class="ulchildlink"><strong><a href="rzairrtrelay.htm">Send e-mail through a router or firewall</a></strong><br />
|
||
|
|
An e-mail router is an intermediate system that Simple Message Transfer Protocol (SMTP) delivers mail to when it cannot locate the recipient's exact IP address.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzairneardomain.htm">Restrict relays</a></strong><br />
|
||
|
|
A common concern that you might face is protecting your server from people who try to use your e-mail server for spamming, or sending large amounts of bulk e-mail. To avoid these problems, use the relay restriction function to specify as closely as possible who can use your server for relay.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzairlmtsvr.htm">Restrict connections</a></strong><br />
|
||
|
|
You can prevent the connection of users who might abuse your e-mail server.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzairfilter.htm">Filter e-mail to prevent virus proliferation</a></strong><br />
|
||
|
|
There are times when a well-known virus might be trying to infiltrate your e-mail servers. To help prevent the spread of the virus, you can create filters to look for a particular subject, type, file name, and originator's address in incoming e-mail. The e-mail can then be quarantined or discarded.</li>
