The dovecot antispam plugin is aimed to help in spam systems training.
Consider the following scenario. Your mailbox is flooded with tons of
mail. They are delivered to the configured folders based on the
arbitrary spam system judgement. This judgement is not always correct
or not always what you would like it to be, however. This is where
this plugin comes into play.
All you have to do is move the mail into the correct folder. All the
rest in order to let the spam system know it made an error will be
done automatically by this plugin.
It watches for when you move the mail to some folder and acts
accordingly. The advantage of this approach is that the mail ends up
in the right target folder directly and needs not be touched twice.
The purpose of this mail library is to provide a portable, efficient
middleware for different kinds of mail access. When using the drivers
interface, the interface is the same for all kinds of mail access, remote
and local mailboxes.

uses for it.
mess822 is a library for parsing Internet mail messages. The mess822
package contains several applications that work with qmail:
* ofmipd rewrites messages from dumb clients. It supports a database
of recognized senders and From lines, using cdb for fast lookups.
* new-inject is an experimental new version of qmail-inject. It
includes a flexible user-controlled hostname rewriting mechanism.
* iftocc can be used in .qmail files. It checks whether a known
address is listed in To or Cc.
* 822header, 822field, 822date, and 822received extract various
pieces of information from a mail message.
* 822print converts a message into an easier-to-read format.
mess822 supports the full complexity of RFC 822 address lists, including
address groups, source routes, spaces around dots, etc. It also supports
common RFC 822 extensions: backslashes in atoms, dots in phrases,
addresses without host names, etc. It extracts each address as an
easy-to-use string, with a separate string for the accompanying comment.
mess822 converts RFC 822 dates into libtai's struct caltime format. It
supports numeric time zones, the standard old-fashioned time zones, and
many nonstandard time zones.

whereas real MTA do. The idea is to refuse any mail on first attempt, and
accept it after some time has elapsed.

listing.
