This kind of blocking tends not to be very effective because the spammers change what they send to avoid using the keywords in your list; hence "v14gr4". You might get a more useful answer if you re-phrase your question to "How can I best stop spam being sent through my Postfix server?" – Ladadadada Jul 13 '12 at 7:19
Hold on a moment... You've referred to emails that are sent through your server twice now. Your best bet is to kick the spammers off your service, not to play around with word lists. Spam, after all, is about consent, not content. – RobM Jul 13 '12 at 7:29

Spammers tend to change their wording often to avoid such blocking, so it'll be hard to build a blocking list that will work for a long time. I would have a look at spamassassin, an opensource product that will update its own settings to adapt to the changes that spammers make.

Thanks for your suggestion jenny D but i need a list of words because spamassassin is not required in my mail server because we need to only send mails from it,and speed is an issue. – ACHAL Jul 13 '12 at 7:21
I'm sorry to say that a list of words is highly unlikely to help you. If there were such a list that worked, there would be no spam problem. I think you need to reframe the question. Who is it that you're afraind will send spam? Who is using the server - is it people in your company, or is it your customers, or is it maybe used to send email from forms on a web server, or all three? Whatever solution you come up with will be more complex than a list of words and will depend on what type of spam problem you're trying to solve. – Jenny D Jul 13 '12 at 7:26
ok thanks for your help i will take a look at spamassassin. – ACHAL Jul 13 '12 at 7:28
