<P><FONT SIZE=2>O MTA Exim (<A HREF="http://www.exim.org/" TARGET="_blank">http://www.exim.org/</A>) oferece mecanismos</FONT>
<BR><FONT SIZE=2>interessantes pra controlar esse tipo de abuso.</FONT>
</P>
<P><FONT SIZE=2>Por exemplo:</FONT>
</P>
<P><FONT SIZE=2>recipients_max:</FONT>
</P>
<P><FONT SIZE=2> If this option is set greater than zero,</FONT>
<BR><FONT SIZE=2> it specifies the maximum number of original</FONT>
<BR><FONT SIZE=2> recipients for any message.</FONT>
</P>
<P><FONT SIZE=2>smtp_ratelimit_hosts:</FONT>
</P>
<P><FONT SIZE=2> Some sites find it helpful to be able to limit</FONT>
<BR><FONT SIZE=2> the rate at which certain hosts can send them</FONT>
<BR><FONT SIZE=2> messages, and the rate at which an individual</FONT>
<BR><FONT SIZE=2> message can specify recipients. </FONT>
