I have used two mail server (Exchange 2013 and Linux sendmail) for mailing in the same domain like abc.com.
I have converted authoritative domain in to internal relay for sending mail in Linux mail user, and create a send connector point to Linux mail system as a smart host. in that case my exchange user send mail to Linux user and internet via Linux smart host,
then I create a receive connector in exchange server for receiving mail from Linux mail system as edge transport custom connector & permission set to anonymous, when Linux user send mail to my exchange user it queued in my exchange message queue and the error is:
Last Error:A local loop was detected.
What's the problem?
