Yes, you start by 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.
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.
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.
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.
This message has been scanned for viruses and
dangerous content by the Inexcom system Scanner,
and is believed to be clean.
