Initial configuration
When you first launch Sylpheed, the configuration wizard guides the user by adding mail accounts. The email address, server type (POP3 or IMAP), host name, port and authentication details are requested. It is recommended to activate the TLS encryption as long as the server supports it, which is done by marking the option «Use SSL / TLS» and selecting the appropriate port (993 for IMAPS, 995 for POP3S). Subsequently, signatures, automatic responses and filtering rules can be defined to organize the inbox according to criteria such as subject, sender or keywords.
