## Mailing Lists

Instead of using the aliases file, mailing lists may also be managed by means of files in the /usr/lib/smail/lists directory. A mailing list named nag-bugs is described by the file lists/nag-bugs, which should contain the members' addresses, separated by commas. The list may be given on multiple lines, with comments being introduced by a hash sign.

For each mailing list, a user (or alias) named owner-listname should exist; any errors occurring when resolving an address are reported to this user. This address is also used as the sender's address on all outgoing messages in the Sender: header field.
