    Exim - "550 No such recipient here" when two-way forwarding

    Hi All,

    I updated exim with config:
    ./build update
    ./build set exim yes
    ./build set eximconf yes
    ./build set eximconf_release 4.5
    ./build set spamassassin yes
    ./build update
    ./build exim
    ./build exim_conf

    Now I have:
    Exim 4.91
    dovecot (0719df592)
    DirectAdmin 1.532
    and little problem after update...

    I have created two e-mail accounts:

    In the case with forwarders configuration:
    1. ->
    2. y@domain,com ->

    I can not send a message to or
    Server returns:
    '550 No such recipient here'.

    It worked before (accounts were receiving messages each other).

    Any ideas why it stopped working?

    I'm having the same issue with forwarders after migrating to DA from cpanel all the forwarders are giving the "The Mailbox doesn't exist" or "Address not found"

    Couldn't this be because you are creating a loop? From x to y, and y forwards the mail to x, upon which x forwards this again to y.

    What happens without forwards, can you send mail from to or does the same error occur?
    And what does /var/log/exim/rejectlog and paniclog say?

    It could also be caused bye to the last exim.conf update.
    Greetings, Richard.
