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?

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
that this alert is recorded is the same that
registered smtp connection in the maillog arquive
my postfix server.
The source IP address in snort's log is equal the
destination IP address in the maillog to smtp
My smtp server is a Postfix version 1.1.3.
This alerts can to be generated by my mail server
it sends mails?
Is this alerts a false positive?
Thanks by help
