<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">I've setup MailScanner at an ISP environment
and it works very well.</font>
<br><font size=2 face="sans-serif">Our core mail servers run standard exim
and for clients who pay for </font>
<br><font size=2 face="sans-serif">virus/spam scanning their mail gets
re-routed to the mailscanner box (only about 20 companies)</font>

<br>
<br><font size=2 face="sans-serif">I've looked at our MRTG stats ...</font>
<br>
<br><font size=2 face="sans-serif">On average we process 25 000 (1.4Gigs)
Mails per day, the stastic I am concerned about is on average there are
111 Mails in the incoming queue</font>
<br><font size=2 face="sans-serif">This is the only process I need to streamline
and make more efficient, the rest of the stats are fine. Does anyone
have any recommendations</font>
<br><font size=2 face="sans-serif">on how to get MailScanner to process
the mail quicker so there is not more than say 20 mails in the incoming
queue on average.</font>
<br>
<br><font size=2 face="sans-serif">Also, I am considering replacing our
core mail servers and replacing them with clustered MailScanner solutions
- the problem I have is that</font>
<br><font size=2 face="sans-serif">I need the quarantine directories to
be the same on all servers and their mail boxes. I have considered
setting up an additional three</font>
<br><font size=2 face="sans-serif">MailScanner machines NFS mounting a
Network storage device... however this comes back to the point of single
failure if the Network storage</font>
<br><font size=2 face="sans-serif">device goes down. Can anyone perhaps
shed some insight on their clustering setups?</font>
<br>
<br><font size=2 face="sans-serif">Thanks in advance!</font>
