Need help with setting up a Catch-All-account (getmail MultidropPOP3Retriever)

Okay, now I got to a solution that works:

If I

  1. add all configured mail accounts to the 20accounts section of /etc/postfix/virtual and do a postmap /etc/postfix/virtual as described here (this should no more be necessary when the corresponding bug is fixed);

  2. use sendmail instead of dovecot-lda in the getmail configuration as suggested by @filippo_carletti, see second post.

then all works as desired: E-Mail from the internet to existent users is delivered to their accounts and E-Mail to non-existent users is delivered to the account defined in “Accept unknown recipients”. :grinning:

Thank you @filippo_carletti and @davidep for your support! :trophy:

Davide, can you please explain your concerns with Filippos suggestion to use sendmail?
