Case Creation in Trigger

Hi,
I have to customize Email to Case . Please help me.
My scenario is,
If my domain name is filled with values in accounts and based on that email field is filled in Contacts, then I need to create Case through Email to Case.But here my problem is Email is not firing through this trigger.
Trigger UpatestatusonCase on EmailMessage (before insert) 
{
        List<Contact> lstcon = new List<Contact>();
        List<Account> lstacc = [ Select id,Name from Account where Domain_Name__c ='www.techlab.com'];
        if(lstacc.size() > 0)
        {      
        lstcon= [Select id,Email,AccountId from Contact where AccountId =: lstacc[0].id and Email = 'tech@techlab.com'];
        }
        if(lstcon.size() > 0)
        {
        for(Contact con : lstcon)
        {
        String stremail = lstcon[0].Email;
        List<EmailMessage> em= new List<EmailMessage>();   
        em=[select id,parentid,FromAddress from EmailMessage where id =: em[0].id and FromAddress =: stremail];
        system.debug('1'+em[0].FromAddress);
        //String emid = em[0].Parentid;
        if(em.size() > 0)
        {
        system.debug('2passed');
        List<Case> cs= new List<Case>();
        for(EmailMessage e : em)
        {
            if(e.FromAddress != '')
            {
                 cs.add(new Case(Subject = e.Subject,Origin = 'Email',Status = 'New',Description = e.TextBody,SuppliedEmail = e.FromAddress));
            }
        }
        insert cs;
        
        
       }
       }
       }
     
  
}

Thank You

If you are trying to access the email that should call this trigger, you will need to use Trigger.new. See below: 
Trigger UpatestatusonCase on EmailMessage (before insert) 
{
    List<Contact> lstcon = new List<Contact>();
    List<Account> lstacc = [ Select id,Name from Account where Domain_Name__c ='www.techlab.com'];

    if(lstacc.size() > 0)
    {      
        lstcon= [Select id,Email,AccountId from Contact where AccountId =: lstacc[0].id and Email = 'tech@techlab.com'];
    }
    if(lstcon.size() > 0)
    {
        List<Case> cs= new List<Case>();
        for(Contact con : lstcon)
        {
            String stremail = lstcon[0].Email;   
            system.debug('2passed');
            
            for(EmailMessage e : Trigger.new)
            {
                system.debug('1'+em[0].FromAddress);
                if(e.FromAddress != '' && e.FromAddress == stremail)
                {
                     cs.add(new Case(Subject = e.Subject,Origin = 'Email',Status = 'New',Description = e.TextBody,SuppliedEmail = e.FromAddress));
                }
            }
       }
       insert cs;
   }
}

Hope that helps

Hi John,

Thanks for you reply..But still having same problem.
John PipkinJohn Pipkin
turn on the debug log. Is this trigger executing at all?
dev_sfdc1dev_sfdc1
My trigger is firing based on the above given mail id its working.But if I change anyother mail with other domain name also creating the cases automatically, at this point. How can I prevent other domain or mail to stop creating cases through Email to Case customisation..
Please help me.
Thank you.

Is the other domain set up as an email in email-to-case standard functionality?
