[IMail Forum] OT: IP address appears in header with sender info

[Geof Tillotson]

So, here's something that I've wondered about off and on for a while now, it's not really critically important, and it is off-topic for the Imail list, but it seems to me that many of you have a deeper understanding of the whole emai world than I so I thought I would ask.

When a client on our network sends and email, using Outlook, the ip address of their computer is included in the header.  This ip address then goes everywhere the email goes.

Does anyone know why?  Also, is there a way to suppress it or replace it with something else?

I have included a header snipet below with the line I'm interested in highlighted.
