When the cache fills up, dnscache smoothly discards old cache entries. You can easily configure dnscache to send queries for a particular domain to a particular set of servers, such as ``split DNS'' internal servers behind a firewall. All you have to do is put the server IP addresses into a file named after the domain. The djbdns package includes three servers that publish local host information: tinydns, walldns, and rbldns. Every aspect of configuration was rethought from the perspective of an overworked administrator who has better things to do than play with DNS. tinydns handles basic DNS service. The tinydns-data file format combines the flexibility of zone files with the convenience of modern zone-building tools. Host information is stored in one file. PTR records are handled automatically. Changes can be scheduled in advance, with TTLs handled automatically. tinydns has several load-balancing features. It automatically selects a random set of 8 servers from a cluster of any size. It allows easy removal of dead servers by external monitoring tools. It also supports client differentiation, checking the client's IP address and choosing one of several clusters accordingly. walldns is a reverse DNS wall. It lets firewalled sites access name-checking servers without revealing true host information. rbldns publishes lists of IP addresses, such as RBL or DUL, through DNS. This could be done with a general-purpose server, but rbldns uses much less memory and much less disk space. Databases for tinydns, pickdns, and rbldns are compiled into cdb format. The servers start up instantly, even if the database is a gigabyte or more. While a new database is being compiled, the servers continue to answer queries from the old database. There is no gap in DNS service when the new database is finished.

A user, Joe, types ezmlm-make ~/SOS ~/.qmail-sos joe-sos isp.net and instantly has a functioning mailing list, joe-sos@isp.net, with all relevant information stored in a new ~/SOS directory. ezmlm sets up joe-sos-subscribe and joe-sos-unsubscribe for automatic processing of subscription and unsubscription requests. Any message to joe-sos-subscribe will work; Joe doesn't have to explain any tricky command formats. ezmlm will send back instructions if a subscriber sends a message to joe-sos-request or joe-sos-help. ezmlm automatically archives new messages. Messages are labelled with sequence numbers; a subscriber can fetch message 123 by sending mail to joe-sos-get.123. The archive format supports fast message retrieval even when there are thousands of messages. ezmlm takes advantage of qmail's VERPs to reliably determine the recipient address and message number for every incoming bounce message. It waits ten days and then sends the subscriber a list of message numbers that bounced. If that warning bounces, ezmlm sends a probe; if the probe bounces, ezmlm automatically removes the subscriber from the mailing list. ezmlm is easy for users to control. Joe can edit ~/SOS/text/* to change any of the administrative messages sent to subscribers. He can remove ~/SOS/public and ~/SOS/archived to disable automatic subscription and archiving. He can put his own address into ~/SOS/editor to set up a moderated mailing list. He can edit ~/SOS/{headeradd,headerremove} to control outgoing headers. ezmlm has several utilities to manually inspect and manage mailing lists. ezmlm uses Delivered-To to stop forwarding loops, Mailing-List to protect other mailing lists against false subscription requests, and real cryptographic cookies to protect normal users against false subscription requests. ezmlm can also be used for a sublist, redistributing messages from another list. ezmlm is reliable, even in the face of system crashes. It writes each new subscription and each new message safely to disk before it reports success to qmail. ezmlm doesn't mind huge mailing lists. Lists don't even have to fit into memory. ezmlm hashes the subscription list into a set of independent files so that it can handle subscription requests quickly. ezmlm uses qmail for blazingly fast parallel SMTP deliveries. The IDX patches add: Indexing, (Remote) Moderation, digest, make patches, multi-language, MIME, global interface, std database support.mw@csi.huhttp://www.ezmlm.org checkpasswordi386cea3da44ed844ddbf740296bd5b2323ca22f76e7Password checking softwarecheckpassword provides a simple, uniform password-checking interface to all root applications.
