Just insert a column in the MySQL table with the host relative to the 
domain. This is my configuration on the proxy:

password_query = SELECT users.clear AS password, domains.host, 
'%u*proxy' AS destuser, 'proxy' AS pass, 'Y' AS proxy FROM users,domains 
WHERE users.username = '%u' AND users.enabled = '1' AND domains.domain = 

In the table "domains" I have a column "domain" with the list of domains 
I want to proxy, and a column "host" with the IPof the pop/imap server.
