Sylpheed adopts 3-paned display similar to the popular e-mail clients for Windows such as Outlook Express and Becky. So it is easier to use it on the first time.
The user-interface is constantly improved, and Sylpheed achieves attentive, comfortable operationality.
Especially the operationality of keyboard is taken count of, so you can sequentially read mails efficiently. Of course, you can use easy mouse-only operation.
You can also customize the behavior of mail display in detail.
The stability and the protection of data is taken into account to the fullest extent because they are the most important factors for e-mail clients. Storing several ten thousands of messages doesn't affect the stability. Even if the application is forcibly terminated, there is almost no possibility of the lost of mail, or inconsistent state of mailboxes.
Messages are managed with MH format on which a file corresponds to a message, so you can easily backup, migrate, and process them with other applications. There is also less risk of mail loss when a system failure occurs, compared to formats on which a file corresponds to a folder. Messages are instantly moved or deleted with this format when asked to, so users don't have to perform periodic compaction of mailboxes by hand to prevent the growth of mailboxes.
