Yes, the last line is the important Information:

local_domains is a list, not a string, so the proper syntax (without
macros) is:

domainlist local_domains = pgsql;select domain from tbldomains \
where domain = '$domain' and ... ;

Is it really necessary to add a "DISTINCT" ?

Other question: When should one use the quote function? Of course it is
necessary to do it as often as possible, could there arise SQL injection
attacks with malformed e-Mail headers? (Assuming that the MUA doesn't
reject them because of invalid characters)... It seems to be used quite
seldom in the examples posted here.
