Apex Email Services

Scenario:-

Email services are automated processes that use Apex classes to process the contents, headers, and attachments of inbound email.
In this Example we can create an email service that automatically creates Cases based on Case information.

Step 1:-
------

Create a New Class :- Setup -> Develop -> ApexClasses

  global class blocklist_emailhandler implements Messaging.InboundEmailHandler{
    global Messaging.InboundEmailResult handleInboundEmail(Messaging.inboundEmail email, Messaging.InboundEnvelope env){
        Messaging.InboundEmailResult result = new Messaging.InboundEmailResult();
        String myPlainText='',emailaddr='',prior='',url='',catog='',addremove='';
        myPlainText = email.plainTextBody;
        system.debug(myPlainText+'==================='+email.subject);
        // formatting the Email and storing into the variables
        if(myPlainText.contains('{') && myPlainText.contains('}')){
            string temp=myPlainText.substring(myPlainText.indexOf('{'),myPlainText.indexOf('}'));
            if(temp.contains(',')){
                for(string s:temp.split(',')){
                    if(s.contains('Email address')){
                        if(s.contains('<')){
                            emailaddr=s.substring(s.indexOf('=')+1,s.indexOf('<')-1);
                        }
                        else{
                            emailaddr=s.substring(s.indexOf('=')+1,s.length());
                        }
                    }
                    else if(s.contains('Priority')){
                        prior=s.substring(s.indexOf('=')+1,s.length());
                    }
                    else if(s.contains('URL')){
                        url=s.substring(s.indexOf('=')+1,s.length());
                    }
                    else if(s.contains('Category')){
                        catog=s.substring(s.indexOf('=')+1,s.length());
                    }
                    else if(s.contains('Add/Remove') || s.contains('Add / Remove')){
                        addremove=s.substring(s.indexOf('=')+1,s.length());
                    }
                }
            }
          //  try{
                System.Debug('**************'+emailaddr);
               //Getting Account and Contact using query
                Contact con=[Select id,Name,AccountID,Email from contact where AccountID!=null and Email!=null limit 1];
                 // Owner Should be International - Escalations Queue
                QueueSobject que= [Select Id,Queue.Id,Queue.Name from QueueSobject where Queue.Name ='International - Escalations'];
                //Creating case with the information sent by Email
                Case newcase=new Case();
                newcase.AccountID=con.AccountId;
                newcase.ContactID=con.id;
                newcase.SuppliedEmail=emailaddr;
                newcase.SuppliedName=url;
                newcase.Priority=prior;
                newcase.Type=catog;
                newcase.Add_or_Remove__c=addremove;
                newcase.Subject=email.subject;
                newcase.Status='New';
                newcase.Transfer_to__c='Support Queue';
                newcase.Ownerid=que.Queue.Id;
                insert newcase;
            //}
           // Catch(Exception e){}
        }
        return result;
    }
}

Check if there is Any Custom Fields , then you have to create those fields in your instance as well.


Step 2:-
---------

Create Email Service :- Setup -> Develop -> Email Services

Give Your Email Id in Accept Email From and Route Error Emails to this Email Addresses.
Here you have to Give the Email that from which email your sending the Emails to Sales force.

And Save

Click on New Email Address Button in Below of the Page

Enter your mail Id and Save.

Then You will get one Sales force Email Address.

Step 3:-
--------

Copy that Email Address and And You have to Send one Email the Sales force Email Address,

The Body should be in Proper below format.

Hi,
 Bla..bla..bla................

{
Email address=testemail@test.net,
Priority=High,
URL(S)=www.test2.com,
Category=Movies,
Add/Remove=Add
}


Best
bla..bla..bla..........


Here in B/W '{' and '}' the Data is Impotent. So we should maintain the constant Structure.
After Sending Email,if you can check the case object in your sales force instance.
The Case record is created with the Details of which you have sent through the mail.
The Above Task is Done..

So friends here my main intention is to people should know how to use the Email Services in Sales force.

The above information may be useful to you.
