No, you don't need a '$', but consider that "^.*anl\.gov" will not only
match all the addresses you want to match but also addresses such as
manl.governance at spammer.invalid spammer at zanl.gov and
spammer at anl.gov.cc. I suggest either

  ^.*[@.]anl\.gov$

if you want to also accept sub domains like mail.anl.gov or

  ^.*@anl\.gov$

if you don't.
