Hi,
What is your IS and EDIINT Module version and fix levels?
So did you choose PrimarySMTP as the delivery method and in the TN receiver profile?
Is the email you are sending works fine with regular client:smtp service and can you test it before EDIINT send invokes ?
Can you please elaborate more info on your setup .
HTH,
RMG
