Email Enabled document Libraries in share point

Although its simple and you use best document available on internet by www.combined-knowledge.com

there is only 1 catch that was left in the document and every time configure it stuck with the same issue that we need to configure a virtual SMTP server with the same name as of you DNS name like in my I had project.abcdomain.com now SMTP virtual server be with this named instance, default instance will not work I don’t know but this is what happens to me always and I wasted hours and hours in debugging whole exchange and sharepoint.
