In cases I know of, they get the username and password from responses
to phishing spam.  They have software that can put data to Imp and
Squirrelmail very fast, to send mail.  The software creates an identity
(or is this part done by hand?), changing the sender to a throwaway
free email account, like yahoo or hotmail, and loading the message
text into the signature file.  They usually send to exactly 100
recipients at a time, but it can be fewer.  The total number of
recipients can run to 100,000.
