I'm looking into a solution of providing Lotus Notes email replication for our users when on an external connection. It looks like setting up a Pass thru server is the solution for this, but I can’t find much information or diagrams on how this is configured. Is this the best or only solution for this? I haven’t been able to find out what ports this uses, are there any good articles or diagrams on how this works?
