What is it?

mess822 is a library for parsingInternet mail messages. The mess822 package contains several applications that work withqmail:

• ofmipd rewrites messages from dumb clients. It supports a database of recognized senders and From lines, usingcdb 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 intolibtai'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.
