like a good option. that said the same can be achieved by saving your quarantine

<P class=MsoNormal>hi<O:P></O:P></P>
<P class=MsoNormal><O:P></O:P></P>
<P class=MsoNormal>I want to setup a number of mailscanner serveres that log
to a shared mysql server and that store the mails (I quarantine both non
spam and spam mails) to some sort of shared storage. NFS or some other
solutions. <O:P></O:P></P>
<P class=MsoNormal><O:P></O:P></P>
<P class=MsoNormal>I would like to know how others have done this and what
kind of performance issues your solutions have had if any. <O:P></O:P></P>
<P class=MsoNormal><O:P></O:P></P>
<P class=MsoNormal>if its not a secret ;-) <O:P></O:P></P>

installing Mailwatch and setup a central Mysql server, you can then enable the
RPC process within MailWatch to allow messages to be released from quarantine
from the Mailwatch running on the Mysql server. This is how I run
it.<BR>I don't store the messages that are in quarantine centrally, rather I
store them on the server than scanned them. This way you can maintain
state with the message when it is released which minimises delays when
greylisting is used, rather than tossing them into a central store.
<BR><BR>Since this is self scaling, i.e. you use the server that decided to
quarantine to store the messages, then the system grows by you simpling adding
machines to cope with your mailscanning load. So if you have
enough machines to handle you scanning, then, unless the numbers are huge, any
reasonable database server hardware should cope.<BR><BR>I use a set up six
Athlon 64 FX based machines to scan and a Pentium D 805 based machine to run
the database and it happily copes with millions of emails per month no bother
at all.<BR><BR>Regards<BR><BR>Pete<BR><BR><BR> <BR><BR>-- <BR>This
