AuthenticatedSmtpUsingCourier

Have exim authenticate against courier authdaemon (thanks to Mark Bergsma)

Another (and probably better) way to do this is shown in Q0730

plain:
        driver = plaintext
        public_name = PLAIN
        server_prompts = :
        server_condition = ${if eq{${readsocket{COURIERSOCKET}{AUTH
${eval:13+${strlen:$2$3}}\nexim\n\login\n$2\n$3\n}{5s}{ } }}{FAIL }{no}{yes}}
        server_set_id = $2

login:
        driver = plaintext
        public_name = LOGIN
        server_prompts = Username:: : Password::
        server_condition = ${if eq{${readsocket{COURIERSOCKET}{AUTH ${eval:13+${strlen:$1$2}}\nexim\n\login\n$1\n$2\n}{5s}{ } }}{FAIL }{no}{yes}}
        server_set_id = $1

Brian Candler has contributed a comprehensive configuration for the use of Courier authdaemond, which is uploaded as an `attachment:exim-courier-authconf`_attachment to this page.`attachment:None`_
