awk -F@ '{print $2}' < your_file

or...

perl -p -e 's/^[^\@]+\@//' < your_file

or...

perl -n -e 'chomp; if (/\@(.*)$/) { print "$1\n" }' < your_file

And so on.  ;-)  Each responds slightly differently to malformed
input, so choose and adjust as is appropriate for the mangled files
you're likely to see.
