Did this below in Message Assignment Shape :

mailOut=InMsg;

mailOut(SMTP.DeliveryReceipt)=true;

mailOut(SMTP.Subject) = "Serengeti: Alert" + InMsg.PONum + InMsg.Status;

mailOut(SMTP.From) = "yyyyy@gmail.com";

mailOut(SMTP.SMTPAuthenticate)= 0;

mailOut(SMTP.SMTPHost) = myHost;

mailOut(SMTP.EmailBodyTextCharset) = "utf-8";

mailOut(SMTP.EmailBodyText) = "This is Body " + InMsg.Status;

mailOut(SMTP.SMTPTo) = "xxxx@gmail.com";

And this in Expression shape :

I have set dynamic email setup but I am not able to receive any emails.

But if I try with static SMTP adapter, then I am receiving emails.

What am I doing wrong while sending dynamically ? Please suggest
