"Get account Info" incorrect messages

[^squirrel^]

Hi,

I have an issue with 10.8.5 server not reading the correct figures of emails in a folder.

To explain,

Mail says 2.1k message in Sent folder
Get account info say 4k messages in the folder.

Is there a way of running a command to reindex/calculate the mailstore on the server it's self?

I've run "rebuild" from within the mail client, that didn't work.

Thanks in advance.
