Postfix removes "friendly" Email

Question

I'm running Postfix, Dovecot and Amavis on Debian. Somehow an email from a colleague wasn't delivered and I started to search the logs.

Here is what I've found. I don't know where the problem is.

My domain: mydomain.com
Sender: name.name@foreigndomain.com
Receiver: me@mydomain.com (alias for the mail address: mk@mydomain.com)

Log:

Does anyone have an explanation or solution for this problem?

You ask about a mail that *"wasn't delivered"* but those logs are about a message that (as dovecot confirms) *was delivered* to your `INBOX` folder (though not telling the story what you or your mail client then proceeded to do with it). Please [edit] your question to clarify. — anx, Dec 24 '20 at 09:39
add to the dovecot config `mail_debug = yes` and `debug_log_path = /var/log/dovecot/dovecot-debug.log` and watch the logs. it should now tell you where it stores the mails — Max Muster, Dec 27 '20 at 06:58

the Email was removed from the the que.

qmgr (that is the mail queue) qmgr = daemon manages the Postfix queues.

line Nr. 8 and line nr. 12 are confusing youprobably,
As you can see in line 10 it goes to the inbox. In line 12 it removes it from the que.

if you have some other application deleting it from there is another story. But anyway dovecot placed it in the Inbox.

Thanks for the explanation. I have only one client and the email was never shown in the Inbox. The client only moves the spam to tue junk folder. – Marcel Dec 25 '20 at 13:25
then update your question with a `postconf -n` and a `dovecot -n` I will take a look. – Max Muster Dec 25 '20 at 13:28
Where do you store the mail ? In Dovecot.there should be something like `mail_location = maildir:~/mail:LAYOUT=fs:INBOX=/var/vmail/%u/mail` – Max Muster Dec 27 '20 at 06:41
Your mail has been delivered, but hwo knows where ? Prolly the delivery system has delivered the mail to another folder that the one you consider to be INBOX – Max Muster Dec 27 '20 at 06:46
the mail dir is mentioned in the plugin section. Normally all emails are correctly delivered to their folders /var/vmail/%d/%n/ – Marcel Dec 27 '20 at 11:03
