I've always had an issue with this.  @ should not be a delimiter.  In what
sense does it ever break up tokens except in an email address?  And breaking
up email addresses is like saying everyone on the same street is a criminal
just because one guy is.  The @ should be removed from the set of
delimiters, and that would solve part of the problem.  Now, I'm not saying
that logging the FROM address would be useful, but you already have code to
detect a domain, right?  So, if you were inclined to detect an email, it
would essentially be [a-zA-Z_\-.+]+\@$DOMAIN.
