How can I configure my astaro or rather exim to suspend mail delivery (still accept but not forward them)?
Im planing a big internal mail upgrade, so exim should not be able to send any mails to my internal mta's.
And just shutdown the internal mta is probably not enaugh, could be that during the upgrade it will come up again for testing and more and then astaro would forward all queued mails... but this should not happen..[8-)].
Thanks
