Sendmail Script User Guide:

  • The script is designed to parse the log files to remove all security concerns.


  • it doesn't affect the system significantly


  • it runs under 5.0x perl (not under 4.0x) and it doesn't use particular perl modules


  • the verbosity level of sendmail should be 8 or 9 (not lower or highter than these)


  • To run it:
    % perl sendscript.pl file1 file2 file3...
    where file1, file2, file3 are the files to parse (I've not used the Compress module in the script, since it's not a basic module; so, if your log files are compressed, you should decompress them before the run) and you should also specify the propper path to reach them.


  • In order to have a significant output you should use a 24 hours logs at least (the best way is to use logs which refer to several days).


  • There are 4 output files:
    • codici_clients
    • codici_hosts
    • codici_macchina
    • output_smtp_sendmail

  • About the output files:

    • "codici_clients"file:
      contains the correspondances between the user name and a code. Every user has a different code assigned to them (the user name is kept from the "from" field in the log file)

    • "codici_macchina" file:
      contains the correspondances between the relay machine and a code ( the relay machine is kept from the "relay" field in the first entry)

    • "codici_hosts" file:
      contains the correspondance between the name of the machine that generated the logs and a code

    • "output_smtp_sendmail" file:
      each row consists of 16 fields:

      1. user code
      2. relay machine code
      3. day
      4. month (the month number start from 00->January since the timelocal function accept months numbers between 0-11)
      5. time (the fields 3,4,5 of the output file are related with the first log entry ,ie when the user send the mail to the sendmail)
      6. protocol used
      7. machine that generated the logs code
      8. number of recipients
      9. message size
      10. day
      11. month (started from 00)
      12. time (referred to the delivery attempt)
      13. the total delay between the time the message was recieved and the time it was delivered ( "delay" log field). This value is expressed in seconds.
      14. the amount of time needed in this delivery attempt ("xdelay" log field) expressed in seconds
      15. mailer name
      16. local/remote delivery: code 1->local; code 2->remote

      There's an entry in the output_smtp_sendmail per each mail delivered: this means that I've considerated the mail queued and then sent, mail sent.
