Is the email address always the last field?
If so, a perl one-liner would do - using Perl's auto-split feature (the
-a) option:
$ perl -lane 'say $F[-1]' in.txt
That will read through the file, split the fields, and print the last
field of each line.
You can, of course, redirect the output to a new file using normal
shell redirection, e.g.:
$ perl -lane 'say $F[-1]' in.txt > out.txt
