I am seeing login dictionary attacks on a FreeBSD mail server being
reported. Is there a way to determine the IPs that are doing this

I don't use sendmail, but aren't the login attempts at least logged in
maillog as well? If so, you could use fail2ban to ban them. We do this
with postfix/exim/dovecot/etc.
