I want to have postfix relaying mail to my dovecot, which is running on the same host. My users are defined in dovecot's passwd file under /etc/dovecot/users like this:
[email protected]:{PLAIN}pw.:10000:10000::/srv/mail/domain/user:: When mails are recieved for a user with no system user, I get the following error:
NOQUEUE: reject: RCPT from sender[ip]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in relay recipient table; I configured postfix to relay my mails as follows:
mydestination = $myhostname, localhost relay_domains = btree:/etc/postfix/relay_domains transport_maps = btree:/etc/postfix/transport, $relay_domains address_verify_map = btree:$data_directory/verify_cache local_recipient_maps = smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, reject_unknown_recipient_domain, reject_unverified_recipient The contents of relay_domains and transport are:
domain.tld lmtp:[127.0.0.1] Here is what I tried already:
- Remove my domains from mydestinations
- Set local_recipient_maps to $relay_domains
- Set local_recipient_maps null
- Remove relay_domains from parent_domain_matches_subdomains
I don't really understand where postfix has its recipient table. From my understanding it shouldn't use this with my configuration. From what I read, with smtpd_recipient_restrictions, postfix should send a probe-mail to dovecot to check whether an address exists or not and should forward it if it is.
I highly appreciate any help solving this.
