Your use of word "SASL" is confusing. See http://wiki.dovecot.org/Sasl

But I guess you want your password_query to do different things based on
%s. For example:

select password from users where username = '%u' and service = '%Ls'

%Ls expands to imap, pop3 or smtp. http://wiki.dovecot.org/Variables
tells more about the variables.
