How are you testing?

Who is "iacovelli_mail"? (It doesn't seem to be setup.)

Look at the Sendmail README files.

Number of recipients (after doing aliases).

The unique message ID. This may be generated by the mail client (MUA) or 
if missing by the MTA (Sendmail).

The time it took to transmit the message during the final delivery part. 
This is in hours, minutes and seconds (or with days too). Also see "delay" 
which is the total time from beginning to end.

The delivery agent. "relay" is for relaying to another mail server (maybe 
on same box) and "local" is commonly for saving to a local file.

The priority. (This probably does not matter at all on a non-busy system.)

These are the unique message identifiers assigned by sendmail. You have 
real "queue" files on your system for these also.
