Hello Tony and Zach,
thanks for replying.
We are using smartermail 12.5.
When I check user's disk usage it shows x GB for sent item and y GB for inbox. the total is assumed Z.
When we use IMAP and sync his mail to ost file, all MSGs are sync and number of inbox and sent item is the same in outlook and smartermail, but Z (size) is different. Smartermail is reporting 3 times more!
Is it possible for you to check the same scenario in your lab or home?
I checked it for different accounts including mine on the same mail server. For example, smartermail repors 600MB usage for me, but when I sync it with outlook it decreases to 250MB.
Is there any why to make sure if everything is okay? A user with more than 2000 mails can't check them all before making a backup to a file and then removing mails from the server.
