I'm using postfix 2.3.3 on CentOS 5.3 and have experienced differing results depending on how I have postfix lookup the virtual domains hosted by postfix.
First, for virtual_alias_domains lookup: postmap -q 4test.net hash:/etc/postfix/domains postmap -q 4test.net ldap:/etc/postfix/domains both yield the result 4test.net. I'm using ldap lookup for virtual_alias_maps such that: postmap -q u...@4test.net ldap:/etc/postfix/virtual yields u...@4test.net. If I use virtual_alias_domains = hash:/etc/postfix/domains, everything works as expected. However, if I use virtual_alias_domains = ldap:/etc/postfix/domains, I receive an error "User unknown in virtual alias table" and the mail is bounced. Since I'm holding everything else constant, I'm not sure why hash vs ldap would make any difference. Logs from the directory server indicate the same lookups in both cases (minus the domain lookups where the hash table is used) with the same results. Is this a bug that's been fixed since this is such an ancient version, or am I missing something here? Steve
