Using dynamic SMTP port fails.

I started learning biztalk a week ago and until this moment was able to solve problems by myself but this one is driving me crazy for a second day already and no mater what I do I can’t move an inch forward to solving it.

I have a schema with a two ports. The second port is dynamic SMTP send port. I initialize it in message assignment and expression shapes before but it doesn’t seem to send any message. Event log just says:

A message sent to adapter “SMTP” on send port “Nexum.Labs.Orchestrations_1.0.0.0_Orchestrations.PurchaseOrchestration_SendNewOrderMessageToFreeAssistantPort_d0c0294e0bae7d49” with URI “mailto:[email protected]” is suspended. 

 Error details: The transport failed to connect to the server.

From this error it may seem that smtp host is not set or bad name is provided but I’m pretty sure it works as static port and I even wrote a test application which used SmtpClient class to send an email through that host an it worked just fine. 

I’m using BizTalk 2009 on Windows 7.

My ochestration looks like this:

Receive port

[ Message assigment shape ] Construct shape

Expression shape

Dynamic send port

Message assigment shape has following expression:

ClientRequestAssignedToAssistantInstance = ClientRequestInstance;

//assistant = BusinessLogic.DbHelper.GetFreeAssistnant();

ClientRequestAssignedToAssistantInstance.ResponsibleAssistant.ID = “1”;

ClientRequestAssignedToAssistantInstance.ResponsibleAssistant.FirstName = “1”;

ClientRequestAssignedToAssistantInstance.ResponsibleAssistant.LastName = “1”;

ClientRequestAssignedToAssistantInstance.ResponsibleAssistant.Email = “[email protected]”;

ClientRequestAssignedToAssistantInstance(SMTP.EmailBodyTextCharset) = “UTF-8”;

ClientRequestAssignedToAssistantInstance(SMTP.From) = “[email protected]”;

ClientRequestAssignedToAssistantInstance(SMTP.EmailBodyText) = “You got new client request to handle.”;

ClientRequestAssignedToAssistantInstance(SMTP.Subject) = “New client request”;

ClientRequestAssignedToAssistantInstance(SMTP.SMTPHost) = “test-server”;

ClientRequestAssignedToAssistantInstance(SMTP.SMTPAuthenticate) = 0;

Expression shape:

SendNewOrderMessageToFreeAssistantPort(Microsoft.XLANGs.BaseTypes.Address) = “mailto:” + “[email protected]”;
