Possibly related to a DNS issue. Workaround is to replace the smtp server name with the IP address associated with that name such as 192.162.5.23. Contact your internal IT team if you cannot identify the IP address of your SMTP server.
002

ManagementStudio.Web.Project.Email.EmailBase    CreateSmtpClient - EmailService - CreateSmtpClient. #8e422    


System.TimeoutException: The operation has timed out."


Basically this problem happens when you are not able to connect to the SMTP server and that is why the timeout occurs. There could be several issue why the problem could occur. Do one of the following:
  • Check SMTP address is correct,
  • Check Port settings
  • Check SSL configuration. Check SSL options with Administration->Global settings
003Invalid Email Template for JIT parsing. Email cannot be sentCheck the throttling settings within Administration->Global settings
