Special Forums Cybersecurity how to hide the IP in the email header? Post 6066 by miket2001 on Wednesday 29th of August 2001 09:39:09 AM

Actually I thought about this myself lately... the reason you'd maybe want to change your ip is if your machine is on a multi-homed natted box and recieving mail from an internal LAN. Then it will report the internal address on the header, unless you do some more natting (madness in my eyes, since multiple NATS can be dodgy).

I don't want MR.Hacker to know the ip address of my internal machines ... do I .

Just change the macro in the sendmail.cf... oh and buy the Bat book just for extreme measure Smilie

mailstats(8)						      System Manager's Manual						      mailstats(8)

NAME
mailstats - Displays statistics about mail traffic SYNOPSIS
mailstats [-o] [-C cffile [-f stfile] FLAGS
Do not display the name of the mailer in the output. Use cffile as the name of the sendmail "cf" file instead of /var/adm/sendmail/send- mail.cf. Use stfile as the input statistics file instead of /var/adm/sendmail/sendmail.st. DESCRIPTION
The mailstats command reads the information in the /var/adm/sendmail/sendmail.st file (or in the file specified with the -f flag), formats it, and writes it to standard output. Note also that you can change the location of the sendmail.st file by editing its pathname in the sendmail.cf file. EXAMPLES
The format of the information is shown in the following example, in which the first field (M) contains a number that indicates the position of that mailer in the sendmail.cf file, starting at 0 (zero). For example, the first mailer in the sendmail.cf file corresponds to the number 0 in the mailstats display, the second mailer corresponds to the number 1, and so on. Statistics from Thu Feb 17 11:20:01 2000 M msgsfr bytes_from msgsto bytes_to msgsrej msgsdis Mailer 1 50 77K 1 3K 0 0 local 6 43 59K 58 99K 0 0 smtp ============================================================ T 93 136K 59 102K 0 0 The fields in the report have the following meanings: Indicates the position of the mailer in the sendmail.cf file. Indicates the number of messages received by the local machine from the indicated mailer. Indicates the number of bytes in the messages received by the local machine from the indicated mailer. Indicates the number of messages sent from the local machine using the indicated mailer. Indicates the number of bytes in the messages sent from the local machine using the indicated mailer. Indicates the number of rejected messages. Indicates the number of discarded messages. Indicates the name of the mailer. If sendmail transmits mail directly to a file, such as the dead.letter file or an alias target, the message and byte counts are credited to the prog mailer, as defined in the sendmail.cf file. However, mailstats will still default to var/adm/sendmail/sendmail.st. FILES
