Two points

1. Please don't convey the entire message using the Subject :-O

2.  Try this signature

alert tcp $HOME_NET any -> $EXTERNAL_NET 25 (msg:"Mail sent to at tnt dot com domain"; flow:to_server,established; 
content:"rcpt to|3a|"; nocase; content:"|40|tnt|2e|com"; within:800; sid:10000000; rev:1;)
