Thank you, Thomas.

Hmmnn . . Maybe I've got it wrong, but it didn't find anything in my log files.

Like, everything zero.
I pointed it at the MERCyymm.LOG files in LOGS.

Maybe the logfile format changed in V4.51 ?

I have mailed robert, if no response, I will probably knock-up my own version.
As you mentioned, the log-file has the data I am needing, just gotta extract it.

I have setup the mercury stats to report daily.
In the mass of stats, I find a section entitled :-
    User statistics - sending:

I cannot find the opposite . . .
    User statistics - receiving:

Is there a setting I have missed ?
We are billed for bandwidth consumption, this includes both up and downstream.
It would be nice to get a handle on the incoming messages per user as well.

<bump>Does anyone have a suggestion as to how I may get a handle on the incoming bandwidth/volume ?</bump>

Analyze the System log, it has all the data you need to determine who is getting the mail, the size of the mail and who they are getting the mail from.  This log can be easily imported into Excel as well.  If you keep daily system logs it should not be too difficult to create a daily report.  Rob Corson has also developed a log processor that might help you out here.
