Free imap4 software for linux

rimo lets you execute commands on Unix based systems via an email from a known address sent to an IMAP4 account.

rimo is designed to be run as a cron process; rimo scans the IMAP4 account for new rimo email messages and executes the command specified in them.

The scanned email messages have their flags set to "seen" so that subsequent scans will not re-execute the commands.

The intent of rimo is to allow for job dispatch and control via non-traditional clients such as a cell phone.

Ciphire Mail is an email encryption tool. It works in conjunction with your existing email client. It operates seamlessly in the background and does not interfere with normal email routines.
Ciphire Mail program encrypts and decrypts email messages, and can digitally sign each message to provide authentication and guard against identity theft.
It resides on your computer, between your email client and your email server, transparently encrypting/decrypting and digitally signing your email communication. It runs on Windows 2000/XP, Linux, and Mac OS X.
It is compatible with all email clients using standard SMTP, POP3, or IMAP4 (including SSL/TLS variants and STARTTLS support). It is free for consumers, non-profit organizations, and the press.
Enhancements:
- This version is primarily a bugfix release, and fixes some minor issues in the 1.2.42 stable version.

Animail is a multiserver POP3/APOP/IMAP4 (with or without SSL) mail retrieval utility. As the tittle of this section suggests, Animail can be used with other external filters to combine his filtering skills with the ones already on Animail. Those filters (you can specify any number of them) will be called just after downloading a message and just before delivering it; depending of the return value of some output of that filter the message will be delivered, ignored, or copied to a log mailbox (so you can see if those filters are not deleting important mail). The commands discussed on the examples of this subsection are detailed on the command block reference.
Main features:
- You can activate several filter to message size, maximun number of messages to download, or delete messages on the server based on a set of regular expressions written in a config file if they match the message header (in this case it will only download the header, not the entire message).
- It can be combined with other mail filters (like SpamAssassin or Bogofilter) in a easy, elegant and documented way. This way Animail uses those programs like plugins and can extends without limits his filtering capabilities, aplying those other filters-plugins to the mails just after they are downloaded and just before they are delivered, giving those other filters the change to decide if a mail is or is not spam.
- It allows downloading mail from several mail servers and those can be written to a local mailbox with mbox format, a QMail style directory (unstable version), or better, be resent to a local SMTP like Sendmail (any SMTP is valid).
- It can forward the downloaded mail to another email adress (if we have the SMTP option activated), or to a coma separeted list of adresses.
- We can configure the download order of the messages based on his size (arrival order, first the bigger messages or first the smaller messages). This allows us, for example, to get first the smaller messages so we can start reading them while a multimegabyte message is being downloaded.
- It has a silent mode with redirects all output to the system log instead of to the console. This is useful if we want to make script that periodically checks for mail (2 examples of this scripts are included in the distribution).
- The program output is a lot more friendly that the one of Fetchmail and others MDAs. When it download a message shows the message origin, and a percentual indicator of the download of the message, over a total given in bytes, kilobytes, megabytes, terabytes depending of the message size (tired of huge bytesize digits? tired of dots?) [Current version supports colored output]
- It has a good speed. In a fast computer (x86 350+), working in text mode and with the -t Switch enabled it can be faster than Fetchmail. The faster is the computer, the bigger is the difference. This only applies to local networks, on internet they are equally slow (internet is the bottleneck).
- To quickly configure Animail after installation create a .animail directory on your home dir, copy the file /usr/share/doc/animail/animailrc and edit to your taste.

Twisted Mail project provides client and server implementations of SMTP, POP3, and IMAP4.
These differentiate themselves from the Python standard library implementations both by presenting a much higher-level, easy-to-use interface and in their server components, which allow the implementation of custom servers for each protocol without dealing with protocol-level issues.
Twisted Mail includes a simple demonstration email server which accepts messages over SMTP, stores them in a Maildir arrangement, and can serve them to clients over POP3.
Enhancements:
- The IMAP4 client now properly quotes usernames and passwords when necessary.
- It also handles unsolicited FLAGS responses.
- The IMAP4 server can now parse multiple literals in a single command and to FETCH requests with multiple BODY parts.
- A bug where Deferreds returned from IMAP4 client methods would not receive connection lost notification has been fixed.
- Startup time on OS X has been improved.
- The SMTP server has been sped up.
- The POP3 mailbox API has been expanded to allow Deferreds to be returned in some cases.

MailStore is a tool that is built in python and provides a mail proxy for POP3,IMAP4 and SMTP protocols. However, beyond usual proxies, it makes a backup of all incoming and outgoing email and stores them in a Maildir format.

Emails then can be accessed through an IMAP server run on the same machine using the backup Maildirs as mailboxes.

The idea is to provide a realtime , centralized backup of all incoming and outgoing of an organization without the need of user intervention, especially for organizations that use shared email hosting. Many of this hosting providers allow for only POP3 based access of the email.

Secondly, due to its shared hosting environment , there is limited space hence all email ends up being downloaded directly to the client. Any backup effort has to be taken up by the user on a periodical basis. This is prone to problems due to the fact that users might either forget or a data disaster might happen in between a backup cycle.

With a backup proxy like this all email is always available at the backup proxy. Any backup need be done by the administrator only at the proxy server itself. This we believe to be a much more convenient task then backing up user systems individually.

Secondly the MailStore server will always have all the emails the user has sent or received at any point ,hence the backup will always be current. To access the email, a local IMAP server can be run that will provide the user with access to the email that has been backed up. The user may then add this account to their email client and backup all the email out of it locally. (E.g. In Outlook you would probably export all the email in the account). Following that the user will import back the mail back into its original account.

Thirdly , the system requires minimal administrator involvement. It handles the creation of new maildirs for new domain/user combinations. Hence administrators dont have extra config files to play with whenevr new users are added to the system. Whether a user exists or not is left up to the mailserver that mailStore is proxying.

The mailStore system is built in Python. It has been tested with Python 2.3 and 2.4. Any system which support Python 2.3/ Python 2.4 should be able to run it.

SOPE Application Server is an extensive set of frameworks (16 frameworks, ~1500 classes) which form a complete Web application server environment.
Besides the Apple WebObjects compatible appserver extended with Zope concepts, it contains a large set of reusable classes: XML processing (SAX2, DOM, XML-RPC), MIME/IMAP4 processing, LDAP connectivity, RDBMS connectivity, and iCalendar parsing.
The individual frameworks of the package can be used standalone (for example in Cocoa applications) and do not require the application server itself.
For MacOSX developers, the package includes SOPE:X, which contains special Xcode and Cocoa support for SOPE.
Enhancements:
- This release fixes a set of minor bugs.
- It improves the vCard parser, the IMAP4 client library, the MySQL adaptor, and BSD packaging.

KBiff is a "biff" or new mail notification utility. It is highly configurable but very easy to use and setup. It tries to combine the best of the features of most of the "other" biff programs out there.
KBiff supports all major mailbox formats: mbox (Berkely style), maildir, mh, POP3, IMAP4, and NNTP. As of 3.7, it also supports POP3 and IMAP4 with SSL. As of 3.8, it supports CRAM-MD5 and APOP authentication.
KBiff is also part of the KDE project. Among other things, this means that it has support for session managment (it "remembers" the last state it was in before you logged off) and can be docked into the panel.
Main features:
- Pure GUI configuration. No more command line parameters to remember (well, one optional one to make things easier for some people) or strange config files. All settings for KBiff can be done from one setup dialog.
- Session Management. KBiff starts up with the same configuration you left it with.
- Panel Docking. KBiff can be docked into the panel very easily. Handy when you are monitoring several mailboxes and dont have room anywhere else.
- Animated GIFs. You can use animated GIFs as your icons.
- Sounds. KBiff has an option to play .wav files when new mail arrives.
- POP3, IMAP4, NNTP, Maildir, MBOX, MH. KBiff supports all major mailbox formats!
- Multiple Mailbox. KBiff can monitor several mailboxes with one instance.
- Others. KBiff has scads of other options.
Enhancements:
- pdated automake admin dir to compile with latest SuSE
- Updated documentation slightly
