<div id="smartTemplate4-template">Unless you outsource your email
service, I don't recommend outsourcing your spam filtering.<br>
<br>
Your system admins will have some ideas on using greylisting, RBLs
and fail2ban, I recommend seriously entertaining the idea of an
open source solution along those lines.<br>
<br>
Retaining the marked emails may be a service you want to offer,
however that removes the "reject all spam" modus operandi.<br>
</div>
<br>
In my experience, after most of the good open source techniques are
in play, it is the customers being phished for webmail and
submission access that poses the major problem.<br>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just wondering what is everyone doing for
Spam Filtering ? Do you still offer as a service or recommend
your customer to go to a particular provider ?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are you hosting the filtering internally on
your systems, virtual or physical or Outsourced ?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Do you make your customers release/review
any spam or do you do it for them ?<o:p></o:p></p>
