Hi, I have a C# Event Sink which performs operations on emails saved to a public folder. I have a problem that sometimes, the email addresses used in those emails are distribution lists. Hence, I am looking for a way to: 1. Check if it is a distribution list (all i get is an SMTP email out of urn:schemas:httpmail: to, cc prop) 2. Get the members of the distribution list. What would be the best way to accomplish that? Thank you in advance, Alex
