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

Hi,

may be som mailserver admins on the list can give me som hint. Thats not
dovecot related, but I know the knowledg here is enormous.

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

I would check your MTA logs, if you get the size of the message and the 
[number of] recipients.  Do you really want to store outgoing mails, too? 
In mailboxes accessable by IMAP or the like?
