You can do it with no code changes, however here is the "catch"… All of the person record email fields are TEXT fields, thus its looking for a full text match. The "From" field in a Notes email will be in the full canonical format: "CN=First LastName/OU=OrgUnit/O=Org", not the simple joe@user.com format.
So to answer your question, yes, just put in the FULL notes names into the Primary or Alt Email field in the Person record OR change the sImportEmail sub-routine in the CratchitConfigLibrary lotusscipt library to check the name for a Notes names and use a better-looking abbreviated format.
Let me know how you make out.
