Cyrus/Postfix/Amavis Fails

Hi
I needed to switch from a SuSE Leap setup of Cyrus 2.5/postfix/amavisd-new setup to Manjaro.

I could - with many struggles - setup

  • Cyrus 3.10
  • Postfix
  • Amavisd
  • Clamav
  • saslauth

I can access the old imported email and send them to the postfix. I am able to send from OTHER identities to my account emails. If I send emails to other local accounts, I see my sent emails in the “sent folder”. However:

  • the mails are not delivered to the recipient
  • They pass amavisd
  • When they should be delivered to the local account, cyrus says: " status=bounced (host mail.brace.de[/run/cyrus/socket/lmtp] said: 550-Mailbox unknown. Either there is no mailbox associated with this 550-name or you do not have authorization to see it. 550 5.1.1 User unknown (in reply to RCPT TO command))"
    I tried to
  • setup the box freshly with cyradm/cm
  • add the account to saslauth2
  • add/remove the user account
  • reconstruct all mailboxes

Has anyone any idea how to solve this matter?

Thanks
