Where in the database is a project's "send mail from" address recorded?

We just changed the default "send mail from" address, so I want to easily see whether there are any projects that are using a non-default address. We have several hundred projects, and I don't want to visit all of them.

Update: Thanks to Boris's answer, I determined this query:

SELECT pname, propertyvalue 
FROM propertyentry
  JOIN propertystring USING (ID) JOIN project ON ENTITY_ID = project.ID
WHERE PROPERTY_KEY = 'jira.project.email.sender' AND propertyvalue IS NOT NULL

You will need to join the propertyentry, propertystring, and project tables to get this. The PROPERTY_KEY will be:

jira.project.email.sender

Exactly what I wanted. Thanks!
