Remove blackhole from Exim4 user

Question

I am waiting for a very important mail. I have noticed in the logs it is not arriving because of something called blackhole in Exim4.

He you can see the log:

exim[22056]: 2017-06-01 11:42:35 1dGMch-0005jk-KY <= [email protected] H=mail1.comodogroup.com (mcmail2.mcr.colo.comodo.net) [91.199.212.133] P=esmtps X=TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 S=7762 [email protected] T="ORDER #73033027 - Domain Control Validation for mail.mailserver.hu" from <[email protected]> for postmaster[at]mailserver.hu

Here is the /etc/aliases file content:

Can You advice where can I remove this blackhole? The MTA is Exim version 4.84_2 #1 built 02-Jan-2017 18:43:30

In the Exim4.conf the is a part, maybe this is the responsible for it?

blackhole_localparts:
        driver = redirect
        local_parts = devnull : postmaster
        data = :blackhole:

Answer 1

In the Exim4.conf I had to remove the blackhole_localparts section and then it arrived.
