Hi, I have a new information about this case. The receiver mail server is a Merak Mail Server Software 8.0.3. Does someone know this server? Does it make ICMP request during the receiving of the e-mail? Thanks again. --- Paulo <listassec () yahoo com> wrote:
Hi, I am using Snort version Version 2.3.2 (Build 12). I have in my snort logs the alerts: 366 - ICMP Ping *nix 384 - ICMP Ping 368 - Ping BSDtype I investigated my others systems logs and in the time that this alert is recorded is the same that registered smtp connection in the maillog arquive from my postfix server. The source IP address in snort's log is equal the destination IP address in the maillog to smtp connection. My smtp server is a Postfix version 1.1.3. This alerts can to be generated by my mail server when it sends mails? Is this alerts a false positive? Thanks by help __________________________________________________ Do You Yahoo!? Tired of spam?
