Well, you could do a lookup for a "static" address before trying the
actual one, and if LDAP doesn't return something assume the server is
down, and accept the mail:
accept domains = +protected_domains
condition = ${lookup ldap {ldap:[...](uid=test)}{0}{1}}
(LDAP stuff snipped out.)
Or combine both lookups:
deny message = DISABLED!!!
domains = +protected_domains
condition = if{ and {{${lookup ldap "uid=test"}{1}{0}}\
{${lookup ldap "uid=$local_part"}{0}{1}}}\
}
(Pseudo syntax, and I'm never sure where to put curly brackets...)
The latter one might save you the second LDAP lookup, if exim conditions
are "short circuit" operations. (Meaning: If two conditions are combined
with and{}, the second is not tested if the first evaluates "false".)
Don't know that, though.
