Why does it look like word wrap is not working?
A. Word wrapping is a bit peculiar perhaps. You can type lines as long as you like. By the time you send or queue a mail with long lines, Sylpheed will first wrap the lines to the line length you set up, and then the mail is queued. This is more convenient than you think. Once a line is wrapped (hard line breaks are inserted in the text) and you add something in a line there, the next line will move to a separate new line, leaving one or two words from the previous line “hanging there” alone. E.g. This is a long line that is wrapped. Now you add one word in the first line: This is a very long line that is wrapped This would cause you a lot of manual reformatting to get a presentable mail again. Note: As of Sylpheed 0.8.0., active wordwrap has been implemented. You can turn it on in Common Preferences->Compose->wrap on input.
