Assume we are able to design things properly, with a single configuration we get per-user mail and system-wide mail which is capable of working in call cases, whether a user uses an MUA or uses some webmail or whatever. It doesn't matter to the user if they switch MUAs, and the MUA that they want to use doesn't necessarily need to support whatever complicated authentication or sending scheme they wish to use; it just works.[1] > Credentials for authenticated SMTP are typically per-real-person > anyway, so ideally you want per-user configuration. Right; there should be a system-wide default configuration, and a per-person configuration which overrides it (and possibly the option for more complex rules based on From address or similar to handle separate roles or something like that.) > Sending through an MTA does let you press "send" without > connectivity and have the mail server submit the mail eventually, > but without any particularly useful feedback to the user (who can't > easily distinguish between "mail got sent", "mail is still queued", > and "an error occurred, the mail will never arrive"). Because of the way that SMTP is designed, users don't really ever know this anyway... but a properly set up MTA does give at least limited feedback. Don Armstrong 1: I should note that I personally use a custom written nullmailer plugin which uses ssh to connect to my central mail host and then run /usr/lib/sendmail there... granted, that's probably a little bit crazy, but it works great for my laptops which are often operating on networks which try do all sorts of crazy things to outgoing mail. Some people on this list are probably doing other similarly crazy things. -- Clothes make the man.
