[Exim] deleting undelivered old messages

    Hi Evreybody ...

    I 'm watching the queue and exim is keeping undelivered messages
until 7 day . end of the seven day it is deleting it ...

    My Configuration String is -->

    ignore_bounce_errors_after = 1d
    timeout_frozen_after = 3d

    But I think this deleting process is not originating from frozen
because undelivered mail is waiting in the queue like this ..

    I mean those are not frozen messages but I want to delete all
messages which are older then 3 day ....

    Thanks ....
