Sure. server_condition is expanded, so you can use the power of Exim's
string expansion to use there as many lookups as you like (and as fit in
your memory), e.g. if you want to authenticate [EMAIL PROTECTED] with ldap
and everything else with mysql (using the LOGIN authenticator):
server_condition = ${if eq{${domain:$auth1}{example.com}} \
{ldap-lookup...} \
{mysql-lookup...} }
or even write the lookups you want into a file like
example.com: ${ldap-lookup...}
example.net: ${mysql-lookup...}
and use
server_condition = ${lookup {/path/to/auth-lookup-file} \
lsearch {${domain:$auth1}} \
{${expand:$value}} fail}
(all untested, of course)
Don't forget to check the corner cases (empty user or password,
non-existant user etc.) so nobody can send mail without proper
authentication.
