If the addresses  don't contain any spaces, I'd replace  SMTP with space SMTP and
.rib with .rib space, then use "text to columns" in the Data Menu to split up
the text into the bits you do and don't want. (If you have spaces you'll need to
find a character that doesn't appear in the strings of text.)You'll need to
insert a couple of columns to receive the split text, but they can be deleted
once you have the information you want.
