What is it?
mess822 is a library for parsing
Internet mail messages.
package contains several applications that work with
- 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.
mess822 is fast. For example, extracting 10000 addresses from a 160KB To
field takes less than a second on a Pentium-100.
