SPAMMERS getting recipients?

[Derrick Georgiades]

I am running sendmail 8.12.9 and just created a new aliases.
After only a day I am catching spam for this new address and it has not been
used yet.
How is it possible that they found the address?  I guess they could try the
usual of the users first initial and last name.
Do they just store a database like this: "jdoe, jsmith, etc" and then throw
those against whatever domain they are trying to hit?
