You can define a special program to pick up messages from the default unix mailbox. Usually this is not used, but you can use it. Actually, this information may be wrong. If someone knows better, please let me know.

Local spool lets you define where your local mailbox is located. You can also tell Sylpheed whether or not to filter the incoming messages from that mail spool file. The spool directory defined here is used by all the accounts of the local type, by default it is set to the standard UNIX mailbox location.

Autocheck new mail. When you check this option, Sylpheed will check if there is new mail on the set interval.

Check new mail on startup means that Sylpheed will immediately look for new mail on all the selected accounts when it loads.

Update all local folders after incorporation Well, if you know the use of this option, feel free to write this part...

In the news section you can specify how many articles should be downloaded when opening a newsgroup.

You can choose to use an external program (like sendmail) for sending mail. By default no external program is necessary and Sylpheed can directly send the outgoing messages to a SMTP server.

The sent messages can be saved in the outbox (Sent folder), the name of the outbox folder can be specified for each account (see the account setting section).

The outgoing codeset selection can be changed to force the definition of the character set used in sent mails. The default and recommended value is automatic, so Sylpheed determines the codeset when sending each message.

You can change the signature separator and choose to insert it automatically (unless your signature file already contains this separator). Leave it as it is by default (unless you really need to change it, and are ready to face a religion war), a lot of mail clients rely on this separator to cut the signature when quoting mails, and this one is accepted as the standard one.

If you hate the editor that comes with Sylpheed, you can choose to automatically start an editor of your choice when composing new messages (the editor can be defined in the Other tab).

The wrap settings defines how Sylpheed will wrap long lines. You can choose to wrap quoted messages, wrap as you type, or wrap when sending. You can also change the maximum line length.

The reply settings let you control the way you will reply to mails. If Automatically select account(...) is set, the account used when replying to a message is automatically selected based on the folder the original message is in (as you where already told, accounts can be attached to folders). If Quote message when replying is selected, when hiting the Reply button, the composition window pops up and is filled with either the complete message you are replying to (if nothing is selected in the body of this message) or the selected part of its body. When this option is not selected, the composition window is always empty, and you must cut-and-paste the parts of the original message you want to quote manually.

You can individually define the quotation mark that appears at the beginning of each quoted line when replying and forwarding a message.

You can also define the text that appears before and after the quotation. The format of the quotation contains placeholders for parts of the original message that are explains in the window that appears when hiting the Description of symbols button.

You can change the font used to display the messages. Pressing the button next to the font name field will open the font selection window, then you can select among all the available fonts.

Turning on the translation of the header fields will change the content of the header summary (between the summary and the message pane), and use the localized header fields name based on the selected language (selected by the 'LANG' environment variable). This setting will only take effect the next time you will start Sylpheed.

Selecting Display unread next to folder name will add the number of unread messages next to the folder name in the folder pane (so you can minimize the width of the folder pane and hide the unread column).

You can also control the content of the summary pane. If you choose to display the recipient name for the mail you send, in the From column, for any mail you have sent, the name of the recipient will appear preceded by an arrow (the characters sequence: -->). The Expand threads controls the initial state of the message threads when opening a folder (expanded or collapsed). The Set display item of summary button opens a selection window that contains all the available items to display in the left column, the currently selected items in the right column. Items can be added or removed using the two arrows that appears between the columns. Using the up and down buttons on the right side of the window, you can change the display order of the selected item in the summary window (from left to right).

The message text can use colours to highlight the different levels of quotation and URIs. The colours can be changed by using the colours selection dialog that pops up when pressing the Edit button next to the Enable coloration of messages toggle.

The display of the header summary between the summary and message panes can also be turned on and off (Display header pane above message view dialog).

Display short header on message view and the Edit button next to it, control the inclusion of some header fields in the message view. If the message coloration has been turned on, the addresses that appear in the header part of the message view are highlighted as URIs.

The Line space setting controls the lines spacing of the message view.

Leave space on head. Checking this box will make the start of new lines (unwrapped, where the writer has pressed the Enter/Return key) indent a few pixels. This can be useful to read larger e-mails.

Scroll half page. When enabled, the text in the message view will only scroll half a page instead of a whole page when pressing the space bar.

Smooth scroll. Enabling this box will make the text in the message view scroll in a smooth, sliding way. For the eye this can be pleasing, it is a personal preference.

Select the Resize attached image if you want all the images (attachment) to be resized to fit in the message window.

The Open message when cursor keys are pressed toggles controls the opening of the messages while you go through them in the summary pane using the cursor (up and down arrows) keys. If this toggle is on, each time you press the down (or up) key in the summary window, the current message changes and the content of the message view changes to the content of the newly selected message. Otherwise, the content of the message view does not change unless you press enter (then the message view contains the content of the selected message). This does not change the behaviour of the left mouse button (always selects and open the pointed message).

Open first unread message when entering a folder if selected, when opening a folder, the message view will contain the first unread message of this folder (or the latest message in the order the folder uses for sorting messages). If not selected, the message view remains empty until a message is selected (by changing the current message with the cursor keys or with the left mouse button).

Only marks message read when open in new window leaves the selected message unread (but display it in the message view) until you open it in a new window (double click the left mouse button).

If Execute immediately when moving or deleting messages is not selected, a new button appears in the button bar marked Execute. When deleting or moving messages, they are first marked as deleted or moved but Sylpheed does not move or delete them until you press the Execute button (or the Execute entry of the Tools menu).

The Receive dialog settings controls the dialog that pops up (if you have set Show receive dialog to always) when receiving new mails. The default is to open a pop up window upon reception error unless you select the Dont't pop up error dialog (...) toggle.

The Set key bindings button when pressed, opens a selection window that contains a list of pre-defined key bindings (Mew, Mutt, Old Sylpheed) to change all the key bindings at once. The key bindings can also be changed one by one as described in

Web browser. Here you can enter the name of your favorite web browser (Netscape, Opera, Mozilla, Lynx etc.). Add the %s parameter to the command so Sylpheed knows it has to provide the text you clicked on as the URL that the browser has to visit. The arrow next to the text field can be used to display a scrolling list of predefined URL browsing command lines.

Printing. Here you can define the program that should be used to print. Default is lpr, and the %s is the name of the temporary file that Sylpheed creates for lpr to print. When using the File->Print menu entry to print the selected message, a text window pops up to allow you to change the command used to print.

External editor. You can select an external editor to write your e-mails with, for example vi, emacs or gedit. Note that for text-based editors like vi, you need to define a terminal window, e.g. xterm -e vi %s. Otherwise there is no place that the editor will be able to show up. Here too, the %s parameter is the name of a temporary file that is created by Sylpheed.

Add address to destination (...) when selected, double clicking an e-mail address (in the address book, when the composition window is opened) can be used to add this address to the To: field.

Confirming if you want to exit Sylpheed (or just exit quietly).

Cleaning the trashbox when exiting Sylpheed.

Have Sylpheed ask you to clean the trash before it is done.

Warn you when exiting Sylpheed when there are still messages queued to be sent.

Sender name, address and organization. Signature, extra header fields.

Leave or remove message from server (usefull for debug).

Incoming mails filtering and size limit.
