SNORT daily report

[Maneesh Patel <mnshptl32 () gmail com>]

I am running an apache2 server on Ubuntu 10.04 (with ssh also
running).  I recently installed snort.  I apologize for this
elementary question, but I am having trouble understanding the daily
report e-mailed by snort.  There are various lines such as

  COMMUNITY SIP TCP/IP message flooding directed to SIP proxy
  (ftp_telnet) FTP traffic encrypted

some to my IP address, some from it.  I would like to know what I
should be looking out for, which lines in the report are innocuous and
which might require some countermeasures.  The snort man page does not
shed light on this, as far as I can tell.  Can someone please direct
me to some documentation that clarifies the daily report?
