I've started to see a lot of these errors, albeit intermittently: warning: dict_ldap_lookup: Search error -5: Timed out
Followed by these: NOQUEUE: reject: RCPT from unknown[x.x.x.x]: 451 4.3.0 <[email protected]>: Temporary lookup failure This server is functioning as an internal relay (no local users) and is performing LDAP lookups for internally routed domains. Is this simply a matter of increasing the timeout? Currently I do not have one specified. Also, where is the cache settings on the LDAP query? I assume it would not be looking up [email protected]<mailto:[email protected]> each time it received an email for it within a specified time-frame. Thanks, Rich
