Recently I did an audit of my machine with logwatch and found out that my machine sends around 582 mails everyday.

 STATISTICS
 ----------

 Messages To Recipients:  582
 Addressed Recipients:    582
 Bytes Transferred:       444985
 Messages No Valid Rcpts: 0

 SMTP SESSION, MESSAGE, OR RECIPIENT ERRORS
 ------------------------------------------

Next day

 STATISTICS
 ----------

 Messages To Recipients:  153
 Addressed Recipients:    279
 Bytes Transferred:       8613451
 Messages No Valid Rcpts: 0

 SMTP SESSION, MESSAGE, OR RECIPIENT ERRORS
 ------------------------------------------

How can I audit more to find out the email ids to where did is send, program which schedules this etc?
