Exim can't make lookup for a "static" address before trying the actual one if LDAP is down.
Exim mainlog:
2004-02-13 12:53:04 H=exim.host [ip] F=<mail> temporarily rejected RCPT <email>:
failed to expand ACL string "${lookup ldap
{ldap://SERVER/dc=DC1,dc=DC2??sub?(uid=$local_part)}{0}{1}}":
lookup of "ldap://SERVER/dc=DC1,dc=DC2??sub?(uid=test)" gave
DEFER: failed to bind the LDAP connection to server SERVER:389 -
LDAP error 81: Can't contact LDAP server
and exim returns to sender
451 Temporary local problem - please try later
and exim does not accept letter.
Is it possible to configure exim to accept letters if LDAP server is switched off?
