look at the timestamp of the spamhause listing, check exim logs for any
intersting log lines shortly after that. spamhause creates the listing
before replying "250" so their event will show a few seconds earlier
than the delivery to spamhaus.

Sometimes an RBL operator gets control of an abandonned domain
(legitimately) and suddenly historic email addresses are now
spamtraps.

no, it's always port 25. most of that text is for people who have
