If it helps, I find the <wbr /> tag rather useful, not for truncating email addresses, but giving a browser clues where it can put line breaks into a string if something is too long (e.g. in a table).

So you could do something like:

  $email =~ s!(\.)!<wbr />$1!g;

I only mention it because I've found myself doing this a lot..
