DESCRIPTION
    EC is an Internet email reader and composer that can download incoming
    messages from one or more POP3 servers, and send mail directly to a SMTP
    server, or via sendmail or qmail if either is installed.

    EC provides options for configuring user defined mail folders and mail
    filtering by matching text patterns in incoming messages. The program
    stores the incoming messages in folders that you configure, or sends
    them directly to the Trash folder for deletion. With no additional
    configuration, however, EC displays incoming messages in, naturally, the
    "Incoming" folder. (EC capitalizes the first letter of directory names
    when creating folder names.) EC displays the number of unread and total
    messages in each folder on the "Folder" menu. Messages can be moved from
    folder to folder, including the Trash folder, so you can retrieve
    messages that you accidentally delete.

    EC permanently deletes messages stored in the Trash folder after a
    user-configurable period of time (two days is the default). Refer to the
    section, "Configuration Files," below.

    EC also supports encoding and decoding of Base64 MIME attachments, using
    an external filter program included in the distribution package.

USING EC
    EC uses two windows for email processing: the main window where you can
    read, sort, save, or delete incoming messages, and a composer window
    where you can enter new messages and reply to messages in the main
    window.

    If you installed EC and its supporting files correctly (as well as Perl
    and the Perl/Tk library modules), typing at the shell prompt in an
    xterm:

       # ./ec

    should start up the program and display the main window with the
    Incoming mail folder. If you receive an error message that the program
    cannot connect to the POP mail server, use the -v command line switch to
    produce a transcript of the dialog with the server:

      # ./ec -v

    If EC pops up an error message, or refuses to start at all, or spews a
    bunch of Perl error messages all over the xterm, consult the INSTALL
    file once again. If you need assistance with the installation, please
    contact the author of the program. The email address is given in the
    section: "CREDITS," below.

    The functions on the menu bar should be fairly self-explanatory. You can
    view different mail folders by selecting them from the "Folder" menu,
    and move messages from one folder to another by selecting the
    destination folder from the "Message -> Move To" submenu. If you have
    Motif installed, you can "tear off" the menus so they are displayed in a
    separate window.

    The "File -> Browse URL" function pops up a dialog box with the URL
    under the text cursor. If you click "OK," EC opens the browser that is
    named in the .eccconfig file, and loads the URL. If the browser is
    already open or iconified, EC will use that browser window to view the
    URL. EC supports Netscape 4.5-4.7, Opera 5.0, and Lynx in an xterm. If
    you select Lynx, you will probably also need to set the xterm option in
    the .ecconfig file.

    The "File -> Attachments" function opens a dialog window to save
    attachments to disk in the main window. When you select "File ->
    Attachments" from in the composer window, the dialog allows you to
    select files that will be attached to the outgoing message. Refer also
    to the section, "MIME Attachments," below.

    There are a number of options for quoting original messages when
    composing a reply. Refer to the .ecconfig file for information about
    these options.

    EC also uses the X clipboard, so you can cut and paste between windows
    in EC as well as other applications. If a program does not have "Cut,"
    "Copy," or "Paste" menu options, you can select text in the original
    application by holding down the left mouse button and dragging it across
    the text to highlight it, then changing to the destination text window,
    and pressing the middle mouse button (or the left and right buttons
    simultaneously on mice with only two buttons).

  Sorting Messages

    You can select whether to sort messages by Date (the default), the
    sender, or the subject, either newest first or oldest first, by
    selecting the sort field from the "Options -> Sort by" submenu and the
    "Options -> Sort Order" submenu, or by clicking on the headings of the
    message listing.

  Entering Messages

    When you click on the "New" button on the function bar below the
    incoming message listing, or select "Message -> Compose New Message"
    from the menu, a window opens with a new message form with header lines
    for the addressee, the subject, and the name of the FCC (File Carbon
    Copy) file to save a copy of the message in. If you have a ~/.signature
    file (refer to the .ecconfig file to configure this option), EC will
    insert that at the end of the text. You can enter the message below the
    separator line.

    Clicking on the function bar's "Reply" button, or selecting "Message ->
    Reply" from the menu bar, will open a compose window with the address
    and subject of the original message filled in, and the message quoted in
    the text area. There are several options that determine how EC fills in
    reply addresses and quotes original messages. Again, refer to the
    .ecconfig file for information about these options.

    Each message contains header information and body text, separated by a
    boundary line:

      --- Enter the message text below this line. ---

    This line must exist for EC to process the message, but it is not
    included in the outgoing message.

    Outgoing messages require at least the valid email address of a
    recipient to be entered on the "To:" header line.

    You can use the optional fields Cc:, Bcc:, and Reply-To:, either by
    adding them manually above the separator line, or selecting them from
    the "Message -> Insert Field" menu selection.

    EC supports a limited form of address "unfolding," so you can enter more
    than one email address on a To:, Cc:, Reply-To:, or Bcc: line, separated
    by commas. EC will include the multiple addresses in the outgoing
    message's header or will process the message to route it to all
    recipients.

  MIME Attachments

    You can attach Base64 binary encoded MIME attachments to outgoing
    messages by selecting the "File -> Attachments..." menu item in the
    compose window, then selecting the file or files to attach. If you
    select "File -> Attachments" from the main window, EC will show you a
    list of file attachments for the current message, which you can then
    save in their original format.

    When attachments are selected, EC also encloses the text portion of the
    message as a MIME "text/plain" section, and sets the header's
    Content-Type: field to "multipart/mixed." All messages contain the
    required MIME-Version:, Content-Type:, and Content-Transfer-Encoding:
    headers, whether or not the message contains any attachments.

CONFIGURATION
  Configuration Files

    The email client uses two configuration files, .ecconfig and .servers.
    They reside in the ~/.ec directory by default, although you can change
    their names and locations by editing their path names in the "ec" and
    ~/.ec/EC/Config.pm files directly . The files and directory are not
    visible in normal directory listings. Use the "-a" option to ls to view
    them:

      # ls -a ~/.ec

    The .ecconfig file contains user-settable defaults for the program's
    operating parameters using <option> <value> statements on each line. The
    function of each setting is explained in the .ecconfig file's comments.

    You can also edit the .ecconfig file by selecting 'Sample .ecconfig
    File...' from the Help menu. Pressing mouse button 3 (the right button
    on many systems), pops up a menu over the text area. where you can save
    your changes. You must exit and restart EC for the changes to take
    effect.

    The .servers file contains the user login name, host name, port and
    password for each POP3 and SMTP server. EC allows incoming mail
    retrieval from multiple POP3 servers, but only allows one SMTP server
    for sending outgoing mail. The format of each line is:

      <server-name> <port> <user-login-name> <password>

    If there is a hyphen, '-', in the password field, then EC will prompt
    you for the server's password when the program logs on to the server.

    In standard configurations, POP3 servers use port 110, and the single
    SMTP server uses port 25.

    The .servers file must have only user read-write permissions (0600),
    otherwise the program complains. The correct permissions can be set with
    the command:

      # chmod 0600 .ec/.servers

    You must be the file's owner, of course, in order to be able to reset
    the file's permissions.

    The '.servers' file is not editable from the Help menu.

  Mail Directories and Folders

    EC can save messages in any number of user-configurable "folders," or
    directories, and it can move messages between the directories with the
    Message -> Move To submenu. By default, the mail folders are
    subdirectories of the <maildir> setting.

    Assuming that a user's HOME directory is /home/bill, the directories
    that correspond to mail folders would are:

      Option     Value      Path
      ------     -----      ----
      maildir    ~/Mail     /home/bill/Mail
      incoming   incoming   /home/bill/Mail/incoming
      trash      trash      /home/bill/Mail/trash

    The 'Incoming' and 'Trash' folders are required. These directories must
    exist before using EC. The program will not create them on its own.

    EC makes the first letter of folder names uppercase, regardless of
    whether the directory name starts with a capital or small letter.

    All other directories can be configured in the .ecconfig file, using the
    'folder' directive. You must create the directories before EC can move
    messages into them.

  Filters

    You can sort incoming mail by matching the text in an incoming message
    with a specified pattern. Each "filter" line in the .ecconfig file is
    composed of a text pattern, a double equals sign, and the folder the
    mail is to be saved in. The format of a filter line in the configuration
    file is:

      filter <text-pattern>==<folder-directory>

    Because the text pattern is used "raw" by Perl, you can use whatever
    metacharacters Perl recognizes (refer to the perlre man page). Pattern
    matches are not case sensitive, and the folder-directory that the
    pattern matches must exist.

    Because of Perl's pattern matching, you must quote some characters that
    are common in email addresses which Perl recognizes as metacharacters,
    by preceding them with a backslash. These characters include '@', '['.
    ']', '<', and '>'. Refer to the example filter definitions in the
    .ecconfig file.

  Mail Transport Agents

    In additon to an ISP's SMTP server, EC can send outgoing messages to
    sendmail or qmail, if either is installed. In the .ecconfig file, the
    "usesendmail" and "useqmail" options determine which program is used. If
    the value of either is non-zero, then outgoing mail is routed to the
    MTA; otherwise, the default is to send mail directly to the ISP's SMTP
    server, using the information in the ~/.ec/.servers file.

    In most sendmail configurations, either the local sendmail must be
    configured to relay messages, or have a "smart host" defined. The
    comments in the .ecconfig file describe only a few possible settings.
    Refer to the sendmail documentation for further information.

    If the "useqmail" option is set, make sure that you can execute the
    qmail-inject program, which is /var/qmail/bin/qmail-inject in qmail's
    default configuration. EC still connects directly to an ISP's POP3
    server, and uses the system UNIX mailbox, usually
    /var/spool/mail/<user>, for incoming messages.

    The qmail-inject -f option is not implemented. The format of the
    sender's return address can be set using environment variables. Refer to
    the qmail-inject manual page for information.

  Editing the Library Path Names in the Source File

    If you would like to change the path names of library files, use a text
    editor to edit the values of $iconpath, $cfgfilename, $serverfilename,
    and $base64enc at the beginning of the main source file, "ec," and
    ~/.ec/EC/Config.pm.

    The expand_path function expands leading tildes ('~') in file and path
    names to the value of the $HOME environment variable, following the
    convention of the UNIX Bourne shell. Directory separators are forward
    slashes ('/'), so compatibility with non-UNIX file systems depends on
    the Perl environment to perform the path name translation.

PRINTING THE DOCUMENTATION IN DIFFERENT FORMATS
    It is possible produce this documentation in various formats using
    Perl's POD formatting utilities:

      pod2html <ec >doc.html
      pod2latex <ec >doc.tex
      pod2man <ec >doc.man
      pod2text <ec >doc.txt
      pod2usage <ec >doc.hlp

    Refer to your system's manual pages for instructions of how to use these
    utilities.
