      Hello together

      Being freshly migrated to kopano 8.4 from Zarafa after years of use, I was very satisfied so far. After a couple of days, suddenly yesterday one of my mailboxes did not accept mails anymore while others do still as designed. Error message in Mail.log is:

      Aug  4 10:29:22 kopano postfix/local[9549]: 20FC28ABD: to=<user1@kopano.zuhause.xx>, relay=local, delay=0.22,

      I am using dagent via lmtp. When I try this manually with

      cat mail | dagent -vvv user1

      (yes this is pipe but not really relevant for the problem) I get

      Thu Aug  3 22:57:02 2017: [ 6343] [error  ] Failed to resolve recipient user1 (1)

Thu Aug  3 22:57:02 2017: [ 6343] [error  ] main(): deliver_recipient failed 8004010f

      When I do the same with the full EXTERNAL address name

      cat mail | dagent -vvv user1@externaldomain.de

      All is fine

Thu Aug  3 22:58:06 2017: [ 6364] [info   ] Delivered message to "user1", Subject: "<none>", Message-Id: , size 6

      All the alias look imho also fine:

      cat /etc/postfix/virtual_domains
user1@externaldomain.de user1
user1@kopano.zuhause.xx user1
user2@externaldomain.de user2
user3@externaldomain.de user3
webmaster@externaldomain.de user1
postmaster@externaldomain.de user1

      Access to database with user1 is possible, user1 is there and config does not show any pecularities

      I nevertheless assume a problem/challenge in the aliases. Can somebody provide some insight how dagent makes recipient resolution? or any other idea where to look further?

      I am looking forward to your reply

      Br br

      EDIT: Meanwhile, I am somewhat more progressed in the analysis but not solution: Direct lmtp via telnet shows:

      telnet 127.0.0.1 2003
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
220 2.1.5 LMTP server is ready
LHLO user1
250-SERVER ready

250 RSET
MAIL FROM:<user1@kopano.zuhause.xx>
250 2.1.0 Ok
RCPT TO:<user1>
503 5.1.4 Destination mailbox address ambiguous

      Is this then the kopano mailbox or is this on postfix level?

        Hello @bringha ,

        actually kopano-dagent does not resolve aliases, but expects the delivering process to either pass the username or the primary emailadress of the user to deliver the message to.

        I would expect you problem to center around:

        status=deferred (temporary failure. Command output: Unable to open logfile
 '/var/log/kopano/dagent.log' as user 'kopano' Not enough permissions to append logfile '/var/log/kopano/dagent.log'. 
Reverting to stderr.

        seems your delivering process has not the same permissions, that kopano-dagent is running as already.

        Regards Felix

          Thanks Felix,

          I had that permission problem in earlier days a few times but believe to have it fixed; all other users can do with the same permission settings; as it can be seen in my edit, root cause seems to indicate in a somewhat different direction i.e.

          Ambigous mailbox address!

          how can I analyze further because kopano-admin does not show me any pecularities

          Br br

            HI @bringha ,

            Destination mailbox address ambiguous

            means that there are two mailboxes existing with the same email and the mail therefore cannot be delivered.

            Regards Felix
