you can try using the session keyword in your alerts:

alert tcp any any -> any 110 (msg: "Password string"; content: "password"; session: printable;)

  Subject: [Snort-sigs] capturing and inspecting an email!

  Hello all !


        I would like to make a rule not base on a single packet but on the whole sequence of packet forming an email to check for the word "password" and log that email. I have checked the rules and they only inspect at the level packet! How do you use the preprocess Stream4 when writing a rule?


  Can you point out some exemple with preprocess Stream4 and Stream4_Reassemble.
