Common preferences: in this option you will be presented a dialog in which you can select a number of tabs. Each tab represents a specific set of settings in Sylpheed. In the next chapter, these dialog options are explained in more detail.

Filter setting: this option shows you a dialog in which you can set up the filtering rules that you want Sylpheed to process on receiving new e-mails. You first specify on which part(s) of the e-mail Sylpheed has to check, and then you tell Sylpheed what to do. You can move the message to a different directory (including trash to get rid of spam mail). Selecting the destination folder is possible through a browser window that comes up when you press "Select..."

You can choose not to receive the e-mail. Note that this will leave the message on the mailserver of your provider, the message will not be removed!

When you press the "Register" button, the filter rule is added to the list of rules. Do you select "Substitute", then the selected rule is replaced by the information of the setting entered. "Delete" in the end will delete the selected filtering rule.

Please note that you can set up two selections for a rule, which can be "OR'd" or "AND'd". OR means that one of the two selections will have to match for the rule to be executed. AND means that both selections have to match before an action is performed.

To the right of the selection rules you see buttons called UP and DOWN. You can move rules up and down in the list. This will often trigger different behaviour in the selections, so consider the order in which you set the rules.

Template: let your create a new message template. When composing a new message you can then used one of the defined templates and insert it (or use it to completely replace the content of your mail). The templates can contain some special characters that are replaced when the template is used in order to create a dynamic text. Use the symbols button on the templates definition window to see the list of the available symbols.

Actions: let your create new commands to be added to the 'Tools/Actions' menu. An action is a command that processes the select part of a message, the message body or the complete message file. It can be a background process, used as a filter (reads, modifies and replaces a message),...

Preferences for current account: here you can set the specifics for the account you are currently using. Should mail be deleted after fetching, what is the server it comes from, etc. Basically it is the same dialog form as shown in setting up a new account.

Create new account: here you name the account (each account has a recognizable name), you set up your name and e-mail address etc. You set up the type of server you access (POP4, IMAP4, local mailbox, newsserver) and where the downloaded messages have to go (default folder is the inbox). In the RECEIVE tab you select or unselect options, in SEND you can set up how to send your messages. In COMPOSE you can point to a specific signature file, and in ADVANCED you can set up alternate ports for the server, if these exist. (Do not mess with these unless you are sure you have to!!)

Edit accounts: here you can select one of the accounts you created, from a list, and edit the information about them. Note that you cannot edit an account for which you are writing a message at the same time. This to ensure data integrity.

Change current account: here you can select what account you want to use, to write a message. If you have enabled the status bar (in the view menu), the name of the current account is shown in the bottom right corner of the Sylpheed window (in the status bar) and can be changed by a click on it (then a menu appears and lists all your accounts).
