Thank you Viktor, I am familiar with those pages. The fact which I think may be undocumented is that postfix (but not postmap) performs iterative prefix queries, when (and only when?) the table-type is indexed. I really hope I haven't come across as critical; I love this program. I'm only making a helpful observation about the discoverability of the info that Wietse gave me. Perhaps a page with info about the hash/DB table-type (like there is about the LDAP table-type) might help. Or not. -- Jack.
