[Postfixbuch-users] Bounce Mail bei nicht zustellbaren Mails.

[Martin Wibbing]

Hallo,

was muss man einstellen damit bounce Meldungen bei den Absender landen ?

Bei nicht zustellbaren Mail erscheint in der Mailqueue:
6AA9FBA        1678 Mon Jan 27 22:52:53  mwibbing at examble.com
(host mail.examble.com[1.2.3.4] said: 450 4.1.1 <xxx at examble.com>: 
Recipient address rejected: unverified address: Host or domain name not 
found. Name service error for name=localhost type=A: Host not found (in 
reply to RCPT TO command))

die Main.cf hat folgende einstellungen:
myhostname = mx01-sz.examble.com
message_size_limit = 20971520
mydomain = examble.com
smtp_helo_name = mx01-sz.examble.com
smtpd_recipient_restrictions =
# Empfaenger whitelisten?
         check_recipient_access hash:/etc/postfix/access_recipient
# Hosts und Absender blacklisten?

         reject_unverified_recipient,
# Backup MX erlauben!
         permit_mx_backup,
# Alles andere Relaying verbieten!
         reject_unauth_destination,
# Was jetzt noch ist darf durch!
         permit

address_verify_map = btree:/var/spool/postfix/data/verify
transport_maps = hash:/etc/postfix/transport,

mynetworks = 127.0.0.0/8 10.0.0.0/8
relay_domains = hash:/etc/postfix/relay_domains
