Hi all! I am just looking for some views here. Obviously, there is the JavaMail standard, which defines a standard API for two things which are related to email messages: - Transports - Stores So the most common implementations I guess are for IMAP stores and SMTP transports. The IMAP store implementations also allow managerial tasks such as CRUD operations on folders and the like. Now there is a protocol in the IMAP server world called managesieve (see: http://tools.ietf.org/html/draft-ietf-sieve-managesieve-09). This protocol is used to manage Sieve scripts on a mail server remotely. So this is neither a store nor a transport IMO. If this was to be standardized, should that rather be an update to JavaMail (introducing a 3rd item besides store and transport; how could that possibly be called) or would managesieve make for an entirely new JSR? I don't actually believe too much in the latter one. Any comments welcome ... Regards, Torsten
