The original message is successfully delivered to your content filter.

Here's one of your LDAP queries.
Jan 7 19:43:11 f42252se dovecot: auth: ldap(redmine@averlon.loc): *unknown user* Jan 7 19:43:11 f42252se dovecot: auth: Debug: master out: NOTFOUND#0111 Jan 7 19:43:11 f42252se postfix/pipe[14637]: BE0AC30007F: to=redmine@averlon.loc, relay=dovecot, delay=0.02, delays=0/0/0/0.01, dsn=5.1.1, status=bounced (user unknown)
The content filter reinjects via sendmail(1), and the pipe(8) to the Dovecot LDA fails. Your LDAP query is not returning what you expect, or you're not querying for the right thing.

There's another one of your queries, looking up the sender address for delivery of the bounce.

Same thing happens to the bounce. Being undeliverable, your mail is gone.
+++ Tell me what you need as additional info.
Turn off verbose logging in Postfix, as Charles pointed out. I guess it's only the TLS logging that you have made verbose.
Review the Dovecot wiki / wiki2 (you didn't say what version you are using?) page on LDAP.
