Sorry, that got sent prior to my completing the email. I'll try again. /etc/postfix/main.cf alias_maps = append_dot_mydomain = no biff = no compatibility_level = 2 content_filter = smtp-amavis:[127.0.0.1]:10024 inet_interfaces = all inet_protocols = ipv4 mailbox_size_limit = 0 message_size_limit = 40960000 milter_default_action = accept milter_protocol = 6 mydestination = myhostname = mail.domain2.com mynetworks = 127.0.0.0/8 192.168.18.0/24 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname non_smtpd_milters = $smtpd_milters policyd-spf_time_limit = 3600 readme_directory = no recipient_delimiter = + relayhost = smtp_tls_CApath = /etc/ssl/certs smtp_tls_mandatory_protocols = !SSLv2,!SSLv3 smtp_tls_protocols = !SSLv2,!SSLv3 smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, reject_unknown_helo_hostname, permit smtpd_milters = local:/opendkim/opendkim.sock,local:/opendmarc/opendmarc.sock smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_invalid_helo_hostname, reject_non_fqdn_helo_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unauth_destination, reject_unauth_pipelining, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client b.barracudacentral.org, reject_rbl_client dnsbl.sorbs.net, reject_unauth_destination, reject_unknown_client_hostname, reject_unknown_sender_domain, check_policy_service unix:private/policyd-spf, permit smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination smtpd_tls_cert_file = /etc/kopano/ssl/cacert.pem smtpd_tls_key_file = /etc/kopano/ssl/server.pem smtpd_tls_security_level = may tls_random_source = dev:/dev/urandom virtual_alias_domains = virtual_alias_maps = hash:/etc/postfix/virtual virtual_mailbox_domains = domain1.com, domain2.com, domain3.com virtual_mailbox_maps = mysql:/etc/postfix/mysql-users.cf virtual_transport = lmtp:unix:/kopano/dagent.sock
The virtual aliases look like: user1firstname.lastn...@domain3.com user1firstname.lastname user2firstn...@domain2.com user2firstname.lastname user2firstn...@domain1.com user2firstname.lastname user2firstname.lastn...@domain2.com user2firstname.lastname @domain3.com user2firstname.lastname @domain2.com user1firstname.lastname @domain1.com user1firstname.lastname In effect, I have 3 users created for domain1.com. A catchall for domain1 and domain2 to direct to user 1. Ignore domain3 for the time being. For some reason though, all emails are ending up in user1’s Inbox. If I send an email from an external email address to user2firstname.lastn...@domain1.com it ends up in user1firstname.lastname’s email. If I send an email to user2firstn...@domain2.com it also ends up in user1firstname.lastname's email. Interestingly, if I remove the @domain1.com catchall in the /etc/postfix/virtual file, email gets delivered correctly to user2firstname.lastn...@domain1.com and user2firstn...@domain2.com. Postfix logs show (with the catchall): Jun 16 09:53:18 kopano postfix/smtp[8735]: 9665C6C28C5: to=us...@domain1.com, orig_to=us...@domain1.com, relay=127.0.0.1[127.0.0.1]:10024, delay=3.9, delays=2.2/0.01/0/1.6, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 4DFA46C28E1) Can anyone point me in the correct direction please. I have spent a couple of days on this trying to work out where I have gone wrong and I am mystified. Happy to provide a more full-featured config if that helps. Cheers, David
