FEATURES

Multiple Languages/Multiple Charsets

Open WebMail current supports more than 30 languages. It is also quite easy to add new language to Open WebMail if yours is still not supported. Open WebMail also has well support for language with more than one charsets. First, a default charset for the language is assumed. If a message is written with charset other than the default one, Open WebMail will convert the message to the default charset automatically.

Fast Folder Access

Folder access performance is greatly improved through the use of dbm (a simple database provided by perl). When a mail folder is selected in the folder view, Open WebMail will parse the mail folder file and cache the parsed result to a dbm. This dbm is reused whenever the user wants to access the folder. The dbm cache eliminates the scan of an entire folder for every access, a significant benefit when dealing with a large folders. The dbm is automatically synchronized with any changes to the folder itself; the dbm update is incremental if the folder modification is done by the Open WebMail application itself. The dbm will however be recreated when a folder is found to have been changed by an external program.

Efficient Message Movement

The size of a message will be slightly increased after it is read at the first time because of status change. A large movement of messages may be introduced due to the size change. Also, the user may want to move a group of messages between two folders. The routines for message update and movement have been totally rewritten so that minimal movement occurs, with correspondingly minimal memory utilization.

Smaller Memory Footprint

Much effort has been put into optimizing Open WebMail's memory utilization. The memory footprint of Open WebMail is much smaller than its predecessors when dealing with messages with large attachments (e.g. a 20MB document), as a result of which the application now runs smoothly on a medium sized machine, (e.g. a Celeron 300 with 128MB RAM).

Convenient Folder/Message Operation

Open WebMail supports 'create', 'rename', 'delete', and 'download' operations on folders, and 'move', 'copy', 'delete' and 'download' operations on messages.

Graceful File Lock

Since a mail folder may be used by multiple programs simultaneously, it is necessary to lock the file before accessing the folder. Open WebMail uses a blocking lock with a timeout limit of 60 seconds. It gives the lock a better chance of success than a nonblocking lock, which returns an error if the lock can not be acquired immediately. Open WebMail also supports locking by dotlock file to ensure that the file locking operates correctly on platforms operating with an incomplete implementation of NFS lockd.

Remote SMTP Relaying

With the help of Net::SMTP module, openwebamil can talk SMTP to SMTP daemons on either localhost or remote machine. This gives openwebmail the better compatibility with various smtp daemons. The system administrator also has more flexibility when designing the mail service system.

Virtual Hosting

You can have as many virtual domains as you want on same server with only one copy of openwebmail installed. Open Webmail supports per domain config file. Each domain can have its own set of configuration options, including domainname, authentication module, quota limit, mailspooldir ...

You can even setup mail accounts for users without creating real unix accounts for them. Please refer to Kevin Ellis's webpage: "How to setup virtual users on Open WebMail using Postfix & vm-pop3d"

User Alias

Open Webmail can use the sendmail virtusertable for user alias mapping. The loginname typed by user may be pure name or name@somedomain. And this loginname can be mapped to another pure name or name@otherdomain in the virtusertable. This gives you the great flexibility in account management. For example, you may have john for different domains by actually mapping them to different real user ids.

  john@domain1.com	john1
  john@domain2.com	john2
  john@domain3.com	john3
  

Per User Capability Configuration

While options in system config file(openwebmail.conf) are applied to all users, you may find it useful to set the options on per user basis sometimes. For example, you may want to limit the client ip access for some users or limit the domain which the user can sent to. This could be easily done with the per user config file support in Open Webmail.

Various Authentication Modules

Various authentication modules are directly available for openwebmail, including auth_unix.pl, auth_ldap.pl, auth_mysql.pl, auth_pgsql.pl and auth_pop3.pl. With these modules, openwebmail can be integrated with other systems easily.

PAM support

Openwebmail can also use other sources for authentication through the PAM (pluggable authentication module). Ex: NIS+, NIS, LDAP, Radius.... Solaris 2.6, Linux and FreeBSD 3.1 are known to support PAM. For more information about PAM, please see http://www.kernel.org/pub/linux/libs/pam/

Full Content Search

Full content search with regular expression support is provided. When a user enters a keyword in the search box, the scope of the mail folder is limited to the keyword related messages. This means the user can use the sort or static functions on the search result. The scope limit is released when the user selects another folder or refreshes the current folder.

Strong MIME Message Capability

Most webmail packages present MIME messages poorly compared to traditional POP clients. Open Webmail presents MIME messages in an attractive format comparable to that presented by Microsoft Outlook. It does this through supporting unlimited levels of attachments and cid object cross-reference inside attachments. Open WebMail also supports uuencoded block inside messages, and displays those uuencoded blocks as if they were normal attachments.

Draft Folder Support

This feature enables the user to write a message in a number of stages, even over several days. The user can save an unfinished message into the draft folder and continue editing at any time.

Reply with Stationery

Serveral stationeries could be defined. It enables the user to quickly reply mail with the same answer.

Spelling Check Support

The spelling check in Open WebMail is very user-friendly and powerful: It makes suggestions for mis-spelled words, and the user can correct the errors very easily by selecting one of the suggestions from a drop-down menu.

Calendar with Reminder/Notification Support

The user can keep track of their appointments, meetings, birthdays, whatever, with the build-in calendar in Open WebMail. This calendar provides serveral views, including year view, month view, week view and day view, so the user can browse their scheduled events very esaily. There is also reminder support for scheduled events, user can specify the days that the reminder shoud look ahead and the first 5 upcoming events will be displayed in the top of mail folder view. If the user want the event reminder to be available outside the webmail system, he can also specify a notification email address, eg: the one used by mobile phone, for each scheduled event, so he can get notification of these events on his mobile phone.

Webdisk Support

The webdisk module provides a web interface for user to use his home directory as a virtual disk on the web. It is also designed as a storage of the mail attachments, the user can freely copy attachments between mail messages and the webdisk.

The / of the virtual disk is mapped to the user's home directory, any item displayed in the virtual disk is actually located under the user home directory.

Webdisk supports basic file operations, eg: mkdir, rmdir, copy, move, rm, file upload and download. Download of multiple files or directories is supported, webdisk compresses the files into a zip stream on the fly in the transmittion. It also handle many types of archives, including zip, arj, rar, tar.gz, tar.bz, tar.bz2, tgz, tbz, gz, z.... The user can compress, decompress or list the contents of archives without copying them into his computer.

POP3 Support

Multiple POP3 accounts can be defined, allowing a single user to fetch mails from a number of mail servers. All messages fetched will be stored in the INBOX folder. Should the fetch operation exceed 10 seconds (due to a slow link or large message for example), the operation will be put into background to avoid an http timeout.

Mail Filter Support

Multiple filter rules can be set to move or copy incoming mails to different folders automatically or even delete them directly. The user can categorize mails from a specific person or spammer, and identify mails containing viruses very easily by defining rules of sender, receiver, SMTP relay, subject, body or filename of attachments.

In addition to the static filter rules, openwebmail has build-in three smart filters: faked smtp filter, faked from filter and faked exe contenttype filter. Faked SMTP filter is useful in filtering messages from spammer, faked from filter and faked exe contenttype filter are useful in filtering messages generated from virus.

Since mail filtering is activated only in Open WebMail, messages will stay in the INBOX until the user reads their mail with Open WebMail. 'finger' or other mail status check utilities may report new mail incorrectly, since they are not aware of filters: A command tool 'checkmail.pl' is provided for use as finger replacement, which performs mail filtering before reporting mail status.

Message Count Preview

When the user pulls down the folderlist menu to select a folder, the counts of new messages and total messages of each mail folder are displayed after the folder name to assist the user in finding unread messages.

Confirm Reading Support

The user can request a 'confirm-reading receipt' for each message sent. When the message is read by the recipient, a receipt will be sent back to this user.

There are too many other small enhancements to mention. You may choose to find them by yourself...

AUTHENTICATION MODULES

Open Webmail has the following modules to support different types of authentication:

Name Description Maintainer
auth_ldap.pl authenticate user with LDAP Ivan Cerrato
Kelson Vibber
auth_mysql.pl authenticate user with MySQL (through DBD::MySQL interface) Alan Sung
