i found strange code in controller:

public modelandview sendemail(@modelattribute(value="emailpasswordform")         bindingresult result, httpservletrequest request){ 

if you want validate form should this:

public modelandview sendemail(     @modelattribute(value="emailpasswordform") emailpasswordform form,     bindingresult result, httpservletrequest request){
