Can't create users on second domain

@uliversal followed a different approach to solve that problem

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

I understand the need to remove it, as you did, for the reasons you explained! However, deleting the domain record corresponding to the machine FQDN produces a broken mail server configuration. I consider it a bug. We should decide how to fix the mail server configuration when it happens, or prevent to delete that specific domain record. I would not apply @filippo_carletti’s proposal: dovecot-lda is safe, and avoid bounces. I’m going to answer in the other thread!
