[Dovecot] 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 Götz-- Götz Reinicke IT-Koordinator

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?

Hi,
no, we have to put all messages in ELM / singel file format on to a networkshare to be collected and processed by a document management system.
We need in and out mails to be saved.
I know there are better/other solutions including good dedublication for mail archiving, but thats how it works.
Cheers . Götz
