im validating some parts
Not good enough. If your form processing code is sending email, it is likely that what you receive is just your copy due to the To: address, but the spammer is sending any number of spam message through your mail server by injecting email address into the header field. ALL external data the is submitted must be validated to insure it contains only expected content.

 

and it aint helping, dont want too

annoying for clientd

Validation won't annoy the client. If he is only entering valid content, he won't even know that validation is occurring. A captcha will annoy a client more than validating input.

 

i defined "number required only"

and still letters are injected

Then your validation code is not working or you are not doing it in your form processing script on the server.
