a really weird problem and as I am a n00b it gets a bit more difficult to find a
solution. </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>Since 6 months ago,
I am the System Administrator of a Tourism Agency. We use an E-mail Scanner in a
server with the following characteristics:</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>This E-mail Scanner
use the MailScanner with Sophos Antivirus and Spam Assasin to filter spam and
scan incoming and outcoming mails for viruses which are then redirected to an
internal MS Exchange Server or to the Internet, respectively by
sendmail.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>One month
ago, the server started behaving erratically. Instead of checking and
sending mails as it normally did, it started queueing mails massively and
therefore accumulating great quantities of them, it got up to 10000 mails queued
up in a single day, therefore, no one recieved a single mail. After many
pointless attempts to repair this problem and seeing that the Travel Agents were
getting a bit mad, I decided to redirect the MX server of our domains in the DNS
to the firewall, so that our E-Mail Scanner server didn't recieve more mail,
which was only going to contribute to making the problem worse, more
incoming mails, more queued mails.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=725004715-19102007></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>With this, the
server started sending the queued mails and mail traffic was restored with
the difference that mails weren't scanned at all(they were no longer passing
through the MailScanner Server). When the mail queues were empty again, I tried
to reestablish the scanning service, but the problem appeared
again.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>I don't have a clear
idea of what can be causing this problem. The machine is pretty old, but the
former administrator told me that it had never had problems. I think that
perhaps we are being Spam Bombed and perhaps the System poor processing
capabilities cannot resists the increasing traffic and therefore it gets stuck
and keeps enqueueing mails.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>Please if anyone can
guide me I'll appreciate it,</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=725004715-19102007>Sorry if my English
is a bit rusty, it is not my native language, therefore if you need me to be
more clear or try to give more details of something, don't hesitate to ask
so.</SPAN></FONT></DIV>
