Hi,

I am trying to send a notification email whenever a case is created with the attachments that were included in the email which created the case. I am able to get the code developed and it sends the notification email but the attachment is not getting through please help

trigger EmailNotification on Case (after insert, after update) {
    for(Case c : system.Trigger.New) {
//        if(c.Notified__c == true) {
            List<EmailTemplate> listET = new List<EmailTemplate>();
            List<User> listOwner = new List<User>();
            List<Attachment> listAttch = new List<Attachment>();
            listET = [select Id, Name, Body, Subject from EmailTemplate where Name = 'Support: Case Assignment Notification'];
            listOwner = [select Id, Name, Email from User where Id = : c.OwnerId];
            listAttch = [select Id, Name, Body, ParentId, ContentType from Attachment where ParentId = : c.Id];
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            Messaging.EmailFileAttachment emailAttch = new Messaging.EmailFileAttachment();
            if(listAttch.size() > 0) {
                for(integer i = 0; i < listattch.size(); i++) {
                    emailAttch.setFileName(listAttch[i].Name);
                    emailAttch.setBody(listAttch[i].Body);
                    emailAttch.setContentType(listAttch[i].ContentType);
                }
                mail.setFileAttachments(new Messaging.EmailFileAttachment[] {emailAttch});
            }
            string[] toadresses;
            for(integer j = 0; j < listOwner.size(); j++) {
                toadresses = new string[] {listOwner[j].Email};
            }
            mail.setToAddresses(toadresses);
            mail.setReplyTo('spprtemail5@gmail.com');
            mail.setSenderDisplayName('SupportEmail');
            for(integer k = 0; k < listET.size(); k++) {
                mail.setSubject(listET[k].Subject);
                mail.setHtmlBody(listET[k].Body);
            }
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});
//        }
    }
}
