Get IP from e-mail

Good morning, This is the first time I use this forum, once all the other answers I could find on google, however, I couldn't find t开发者_JS百科his one.

I am using Openpop.net in VB.NET to develop a service to send and capture e-mails and I need to put, among other informations, the Origin and destination IPs from the e-mail, but I can't find it how to do it.

Could Someone help me?

Thanks in advance

the IP may be (if it is) in MIME headers. Look for X-Originating-IP or Received header.

I've managed to get the IP with a .NET API specific for that.
