Exim is an MTA... a Mail Transfer Agent. It receives mail from the wire and either puts it into a mail box or sends it to another MTA.

Exim has many types of lookups. They all follow the same basic syntax. (you won't find this else where - I looked)...
${lookup [type of lookup] {pass} {fail}}
type of lookup covers many things and those constructs are covered in there own namespace. The point here is the structure of the lookup.
The pass value is returned if type of lookup succeeds. The fail value is returned if it doesn't.
A real life example. This is from a router..:
condition = ${loolup \
mysql{ \
SELECT username \
FROM myusers \
WHERE username = ${quote_mysql:$local_part} \
} \
{yes} \
{no} \
}
The slashes are continuation characters... you knew that.
If the query is successful it will return yes otherwise it returns no which would cause the router to fail.
