sendmail, 4th Edition

ListManager

According to its author, Murray S. Kucherawy, the ListManager system “is written entirely in C, so it’s faster and more efficient than mailing list systems based on scripted languages. Rather than flat files, it uses fast B-tree databases courtesy of Sleepycat Software for faster performance.” This is the mailing list software used by sendmail.org. Among the features claimed on its web site are:

• Automatic mail-alias table updates

• Moderated, private, invite-only, and “hidden” lists

• List archiving, with access controls and lifetime limits

• Subscription confirmation, new subscriber probation, and subscriber renewals

• Address validation check levels: none, syntax only, MX, and SMTP

• HTTP interface and extensive help

• Password security on subscriptions and list modifications

• Arbitrary file storage, and Unix mailbox-format archives

• MIME attachment filtering and loop detection

• Automatic subscriber addition features

• Quotation limiting, access control lists, digest sorting, and list inclusions

• Subscriber domain matching

• Rotating footers, and separate headers and footers for digests

• Crontab-like digest distribution settings

• Distribution of digests by size, time, or number of submissions

• Welcome and farewell messages

• Domain masquerading

• Powerful command-line features such as “foreach” and scripting
