<div class="MsoNormal" style="MARGIN: 0mm 0mm 0pt"><span lang="EN-US"><font face="Century" size="3">The system is processing over 200,000 emails per day, BUT most of emails (about 95%) are junk / spam and if queue gets over 10,000 it’s freezes all delivery
process.</font></span></div>
<div class="MsoNormal" style="MARGIN: 0mm 0mm 0pt"><span lang="EN-US"><font face="Century" size="3">Are there any parameters that I can tweak to speed-up the delivery process?</font></span></div>
