correct and yes it's an email hosted by DreamHost. This is the message I keep receiving from support:
We have received notification that your e-mail
address has been compromised by spammers and was being used to send out spam . This means that your user's password has likely been compromised.
Your user's password has been changed to a random string to prevent the intruder
from logging back in. Please do NOT change the password back to what it was previously! Going
forward we need you to:
1) Ensure that you (and all of your users) have active and up-to-date
virus/malware screening on all computers they use to connect to
DreamHost. Infected computers are often how strong passwords are stolen.
2) Pick a new password for this user via the DreamHost control panel
under "E-mail" -> "Manage Addresses" -> "Edit". Your new password should
not bear any similarity to the old one, should not be one you've used
with any other online service, and should not contain any guessable
