That is so true. If you find a spammer, lock the account and contact the
rightfull owner after you cleared your mailqueue.
If he got the smtp password, the attacker will have the mainpassword too
, which will get even worse than sending spam.

They don't know, they steal it via a virus, trojan horse or phising attempt. Which must alert the accountowner to find out how he got hacked, in his own interest.
