I am trying to relay mail thru our server

I add to the email domain

but am getting the following error

Recipient address rejected: User
unknown in virtual mailbox table (in reply to RCPT TO command)


We do relay other domains thru this server

Re: Relaying Domain mail

Does this recipient exist on your server? It's better to paste original related log here instead of the snippet you think it's helpful enough.

Postfix reports it cannot find this user in LDAP/SQL database. Could you please show us output of command "postconf -n" here to help troubleshoot?

Also, show me output of below command:

# cd /etc/postfix/mysql/
# for cf in $(ls *.cf); do echo ${cf}; postmap -q malinda@remax-helderberg.co.za mysql:./${cf}; done

Re: Relaying Domain mail

The external Postfix server uses a flat file for the users and their password

The mail works well this way
