Sorry, I disguised the client, server, domain and user names in the logs (all other portions are intact). If 'USER1' user is really not found, postfix/smtpd should have rejected - but this is not the case. Thousands of emails get through for all the users, but once in a while postfix/local fails to find the user in the alias tables (as shown above). -> O/p of "postconf -n" command alias_database = hash:/etc/postfix/aliases hash:/etc/postfix/aliases.shared hash:/etc/postfix/aliases.users hash:/etc/postfix/aliases.lists hash:/etc/postfix/aliases.dllists alias_maps = hash:/etc/postfix/aliases hash:/etc/postfix/aliases.shared hash:/etc/postfix/aliases.users hash:/etc/postfix/aliases.lists hash:/etc/postfix/aliases.dllists biff = no canonical_maps = regexp:/etc/postfix/canonical config_directory = /etc/postfix daemon_directory = /usr/lib/postfix html_directory = /usr/share/doc/packages/postfix/html local_header_rewrite_clients = permit_mynetworks local_recipient_maps = $alias_maps mail_owner = postfix mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man masquerade_domains = !sub1.DOMAIN.com !sub2.DOMAIN.com !sub3.DOMAIN.com !sub4.DOMAIN.com !sub5.DOMAIN.com !sub6.DOMAIN.com !sub7.DOMAIN.com !sub8.DOMAIN.com DOMAIN.com message_size_limit = 41943040 mydestination = $myhostname, $mydomain, sub1.DOMAIN.com, sub2.DOMAIN.com, localhost, localhost.localdomain mydomain = DOMAIN.com mynetworks = 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, /etc/postfix/relay_from mynetworks_style = subnet myorigin = DOMAIN.com newaliases_path = /usr/bin/newaliases notify_classes = resource, software, policy readme_directory = /usr/share/doc/packages/postfix/README_FILES recipient_delimiter = + relay_domains = sample_directory = /usr/share/doc/packages/postfix/samples sendmail_path = /usr/sbin/sendmail setgid_group = maildrop transport_maps = hash:/etc/postfix/transport Thanks, Satish -- View this message in context: http://old.nabble.com/possible-problem-with-postfix-local---tp26939697p26942833.html Sent from the Postfix mailing list archive at Nabble.com.
