Dear all,

 I'm facing a problem with the email event at runtime of the workflow. I have mail events whenever the workflow reach those events the following error is generated in the Error Profile: "Invalid Header Packet Recieved!!" 

 

We are working with exchange 2003. 

 

An other error is being generated on the same step of another process instance:

 "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."

 Thanks

Here are a couple of things to check:


1.  Make sure the Mail Server environment variable has your correct email server.


2.  Check if your email server has rules that reject SMTP requests from servers that are not in an allowed list


Another way I have found to help diagnose these things is to write a quick little .NET utility that uses the System.Net.Mail classes to a test email message.
