xdg-email appears to be for interactive use (it opens the user's "preferred email composer"); I think sendmail would work much better from a script.
Like what I said in another post I think I could use ssmtp than xdg-email or sendmail...
Otherwise, I had the same initial thought, to add to and/or build a wrapper around the existing lftp script.
I'd like to know if there's a code made from lftp to understand when an upload file is finished but certainly I can read it from the log file and I think it couldn't be hard to find a value in a *.txt file and if this value is inside of it to send an email like "ok" otherwise a message with "k.o.".
