Email::Find allows you to find RFC 822 email addresses in plain text.

Email::Find is a module for finding a subset of RFC 822 email addresses in arbitrary text (see "CAVEATS"). The addresses it finds are not guaranteed to exist or even actually be email addresses at all (see "CAVEATS"), but they will be valid RFC 822 syntax.

Email::Find will perform some heuristics to avoid some of the more obvious red herrings and false addresses, but theres only so much which can be done without a human.

Finds email addresses in the text and executes callback registered.

The callback is given two arguments. The first is a Mail::Address object representing the address found. The second is the actual original email as found in the text. Whatever the callback returns will replace the original text.

Email::Store is a framework for database-backed email storage.

SYNOPSIS

use Email::Store dbi:mysql:mailstore;
Email::Store->setup; # Do this once

Email::Store::Mail->store( $rfc822 );
Email::Store::Mail->retrieve( $msgid );

...

Email::Store is the ideal basis for any application which needs to deal with databases of email: archiving, searching, or even storing mail for implementing IMAP or POP3 servers.

Email::Store itself is a very lightweight framework, meaning it does not provide very much functionality itself; in effect, it is merely a Class::DBI interface to a database schema which is designed for storing email. Incidentally, if you dont know much about Class::DBI, youre going to need to in order to get much out of this.

Despite its minimalist nature, Email::Store is incredibly powerful. Its power comes from its extensibility, through plugin modules and hooks which allow you to add new database tables and concepts to the system, and so access the mail store from a "different direction". In a sense, Email::Store is a blank canvas, onto which you can pick and choose (or even write!) the plugins which you want for your application.

For instance, the core Email::Store::Entity plugin module addresses the idea of "people" in the email universe, allowing you to search for mails to or from particular people; (despite their changing names or email addresses) Email::Store::Thread interfaces Email::Store to Mail::Thread allowing you to navigate mails by their position in a mail thread; the planned non-core Email::Store::Plucene module plugs into the indexing process and stores information about emails in a Plucene search index for quick retrieval later, and so on.

rblcheck is a lightweight C program for doing checks against Paul Vixies MAPS Blackhole List and the ORBS open relay list. It works well in conjunction with Procmail for filtering unwanted and spamming bulk email.
The general idea behind RBL-style listings is rapid lookup of IP addresses using DNS (for example, for blacklisting IP addresses because of abuse). Each IP address is reversed and has a domain name attached to it; for example, the IP address 127.0.0.2 would become 2.0.0.127, and then a domain such as "relays.visi.com" would be added to it. You would then try to resolve the result (ie. 2.0.0.127.relays.visi.com); if you receive a positive reply, then you know that the address is listed. Further information can also be queried, such as text descriptions of why the address was listed.
Enhancements:
- Converted to automake/autoconf for configuration, which should make it easier to extend portability
- Added support for checking multiple addresses in one invokation.
- Added support for reading addresses to check from standard input, by specifying an argument of -.
- Changed rbl.dorkslayers.com to relays.orbs.org, due to a change in management.
