WorkFlow get triggered even if we set trigger for item update with SPEmailEventReceiver and workflow attached to same Library

Hi All,

           I have a situation, SPEmailEventReceiver and WorkFlow is attached to same library, WorkFlow is configured to run after item is updated, but soon as the email is received in library the workflow is getting triggered, We have a action to create folder with subject and date and put the attachment with the date folder in SPEmailEventReceiver e.g: once a mail is received in library the SPEmailEventReceiver will create a folder with Subject and then Folder with Date and then put the attachment in the date folder so hierarchy will be subject folder/Date folder/attachment

I have tried to alter the SquenceNumber attribute in Feature Element file to 1 and make the Synchronization as synchronous but no luck.
