I have setup Zimbra in our office as a test to replace our external mail server.
At the moment I have only one account that only sends email using the server and receives using the external server.
On top of that I have one IMAP account that polls fromt the external server and I have important all previous local messages into this account.
My question now is that when I check the server statistics that there were 450 message at 2PM on Sep 7. I don't understand this number. When I check the /var/log/mail.log only a few emails were send and when I check the recepients there were only 14 recepients in total.
I just want to get a realistic idea on the number and size of the total messages that is going through this server.
Could the large nr of messages be caused by Thunderbird scanning the IMAP folders?
Is there any other log that I could check?
