Free email messages software for linux

LAFmessage is a feature-complete library for fetching, parsing, generating and delivering MIME-compliant email messages. The project has C++, JNI (Java) and Win32 COM APIs.
For generating mail messages, LAFmessage provides an object-oriented API that represents all the pieces of a message and allows the caller to assemble them in (nearly) limitless combinations to programatically reproduce any feature that is to be found in interactive mail clients (and a few that arent!). These include:
RFC 822-compliant (non-MIME) plain text email.
RFC 2045-compliant (MIME-compliant) plain text email.
RFC 2045-compliant (MIME-compliant) HTML email.
RFC 2045-compliant (MIME-compliant) attachments, both external and embedded.
RFC 822-compliant user-defined header fields.
Messages can also be parsed from RFC 822 or RFC 2045 format into the same object structure to allow programmatic parsing of message content, saving of attachments, forwarding of whole messages, etc.
For fetching and delivering messages, LAFmessage provides the following features:
- RFC 1939-compliant POP3 system for connecting to arbitrary POP3 servers, retrieving and deleting email messages. Downloaded messages are parsed into the object structure for programmatic handling or presentation to an end user.
- RFC 821-compliant SMTP system for connecting to arbitrary SMTP servers, authenticating and delivering email messages. Messages may be delivered synchronously or queued within LAFmessage for asynchronous delivery. Delivery status is available during batch delivery and optimizations are available to speed delivery such as:
- Multiple recipients per SMTP transaction -- greatly reduces network traffic and mail server load.
- Multiple worker threads to deliver queued messages -- can greatly reduce delivery time.
LAFmessage has the capability to canonicalize strings to render strings safe for insertion into HTML, HTML TEXTAREAs, JavaScript and SQL statements.
LAFmessage presents several different APIs:
- A COM interface for use from COM-aware environments on Win32 platforms
- A JNI interface for use from Java applications on Win32 and Linux platforms
- A C++ interface that can be used directly in new programs by simply including the necessary files on Win32 and Linux platforms
LAFmessage is completely thread-safe and suitable for use from ASP pages.

Message::Style is a Perl module to perform stylistic analysis of messages.

SYNOPSIS

use Message::Style;

my $score=Message::Style::score(@article);
# or
my $score=Message::Style::score(@article);

This Perl library does an analysis of a RFC2822 format message (typically email messages or Usenet posts) and produces a score that, in the authors opinion, gives a good indication as to whether the poster is a fsckwit, and therefore whether their message should be ignored.

Newsmail was created to allow easy news publication to one or more sites, using email messages to insert, delete, and manage news.
It is a simple PHP news ticker that allows you to publish news via email. Newsmail can generate RSS feeds for news matching a given category.
Main features:
- import plain text or HTML email messages with or without attachments, and with or without Markdown syntax.
- store messages in database (currently Postgresql and MySQL are supported, but the PHP code uses Pear::DB abstraction) and attachments in filesystem.
- request a confirmation message before publishing or deleting news.
- require an approvation from a moderator before publishing or deleting news.
- answer to some administration commands directly via email (e.g. news listing, news delete and update).
- generate an RSS feed with news matching a particular category or with category equal to all
Enhancements:
- A small improvement was made to the install instructions.
- An approval option was added, which requires BCC_ADDRESS approval for inserting and deleting messages.
- The approval process uses a randomly generated token password to improve security.
- The database structure was changed to use a token for approval security.
- The MySQL table definition was improved to use INNODB.

Mail::Message::Head::Complete is a Perl module with the header of one message.

INHERITANCE

Mail::Message::Head::Complete
is a Mail::Message::Head
is a Mail::Reporter

Mail::Message::Head::Complete is extended by
Mail::Message::Head::Partial
Mail::Message::Replace::MailHeader

Mail::Message::Head::Complete is realized by
Mail::Message::Head::Delayed
Mail::Message::Head::Subset

SYNOPSIS

my $head = Mail::Message::Head::Complete->new;
See Mail::Message::Head

E-mails message can be in various states: unread, partially read, and fully read. The class stores a message of which all header lines are known for sure.

MailGoose is an off-line mailer package for people who use nail, PINE, elm, Emacs mail mode, or other simple email software. It is particularly useful for laptop users.
You can browse the URLs of your mail spool, mbox, or copy of an email message, create an offline draft reply of an email message, edit your drafts in your favorite editor, create a new
message, or send all pending drafts.
Think of MailGoose as the useful bells and whistles of the big email clients made available to the discriminating console-mode hacker.
Enhancements:
- Documentation and install fixes.

Mail::Message::Convert::MailInternet is a Perl module that can translate Mail::Message to Mail::Internet vv.

INHERITANCE

Mail::Message::Convert::MailInternet
is a Mail::Message::Convert
is a Mail::Reporter

SYNOPSIS

use Mail::Message::Convert::MailInternet;
my $convert = Mail::Message::Convert::MailInternet->new;

my Mail::Message $msg = Mail::Message->new;
my Mail::Internet $intern = $convert->export($msg);

my Mail::Internet $intern = Mail::Internet->new;
my Mail::Message $msg = $convert->from($intern);

use Mail::Box::Manager;
my $mgr = Mail::Box::Manager->new;
my $folder = $mgr->open(folder => Outbox);
$folder->addMessage($intern);

The Mail::Internet class of message is very popular for all kinds of message applications written in Perl. However, the format was developed when e-mail messages where still small and attachments where rare; Mail::Message is much more flexible in this respect.

archivemail is a tool written in Python for archiving and compressing old email in mailboxes. archivemail can move messages older than the specified number of days to a separate mbox format mailbox that is compressed with gzip, or optionally just delete old email.
Maybe some of your mailboxes are quite large (eg, over 10,000 messages) and they are taking a while to load in your mail reader. Perhaps they are taking up too much space on your disk. Archiving old messages to a separate, compressed mailbox will mean:
1. Your mail reader will get a huge performance boost loading and reading your mail.
2. You will be taking up less disk space, since old mail will be compressed. (Mail usually compresses quite nicely.)
3. You wont be confronted with semi-obsolete mail all the time.
If you would prefer to just delete old email rather than archive it, archivemail can do that too.
Main features:
- Support for archiving IMAP, mbox, MH and maildir format mailboxes.
- You can configure the amount of days before mail is considered old -- with the default being 180 days.
- Messages that are flagged important are not archived or deleted unless you specify the --include-flagged option.
- Optionally warn about duplicate Message-IDs in a mailbox.
- You can specify an option so that unread mail is never archived.
- Allows you to store the compressed archive mailboxes in a directory of your choice, with an extension of your choice.
- Support for deleting old mail rather than archiving it.
- Optional ability to archive messages older than an absolute date with the --date option.
- Ability to only archive messages over a certain byte size.

smf-sav is a lightweight, fast and reliable Sendmail milter that implements a real-time Sender e-Mail Address Verification technology. This technology can stop some kind of SPAM with a spoofed senders e-Mail address.
Also it implements a real-time Recipient e-Mail Address Verification technology. It can be useful if your machine is a backup MX for the recipients domain or if your machine forwards all e-Mail messages for your domain to another (presumably internal) e-Mail server. Sendmail Sender Address Validator is written in C.
Main features:
- friendly hosts/networks whitelist;
- SMTP AUTH support;
- strictly RFC-2821 compliant MX callback engine;
- tolerance against non RFC-2821 compliant e-Mail servers;
- blocking of e-Mail messages with a spoofed senders e-Mail address;
- recipients e-Mail address verification with an authoritative e-Mail store in gateway mode;
- slow down of recipients e-Mail address brute force attacks in gateway mode.
Enhancements:
- Whitelisting by a PTR (reverse DNS) record was implemented.
- Whitelisting by an envelope recipient email address was implemented.
- The option to ignore tempfailed results of SAV was implemented.
- The option to refuse email messages from systems that dont accept the null reverse-path was implemented.
- Tempfail and fail results TTL settings were segregated.
- Progressive slowdown of brute force attacks on a recipients email address was implemented.
