CentOS - Nov 2013 - how to calculate mail storage/traffic used

Hi,

we have to setup a server which gets a copy of all messages send and
received by our mailserver as a 1:1 copy. Mails send to multiple
recipients should be calculated and saved per user. (great if you
usually have lost of mails send to groups of people.)

So no dedublication should be used here. (e.g. save the message and
refer the different recipients to it.)

How can I calculate the current traffic in the best way to extrapolate
the amount of space to be planed for the new server?

We think to have a couples of days to be saved.

	Thanks for any hint or comment. Regards G?tz

You don't say what MTA you are using. If it's Postfix (the default in 
RHEL6), pflogsumm can provide such information from your logs.
