Recipient address rejected:User unknown in virtual alias table 550 5.1.1
Hai All,
I have been getting problem in receiving emails from external accounts . I have set up a Mail Server comprising Postfix, Dovecot, roundcube using centos web panelin the centos 6.8 Server machine. I have no problem sending emails , but the issue comes up when trying to receive emails back from their end to my accounts. Here is the my configuration file:- main.cf:- # postfix config file # uncomment for debugging if needed soft_bounce=yes # postfix main mail_owner = postfix setgid_group = postdrop delay_warning_time = 4 # postfix paths html_directory = no command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix queue_directory = /var/spool/postfix sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man # network settings inet_interfaces = all mydomain =domain.com myhostname = mail.domain.com mynetworks = $config_directory/mynetworks mydestination = $myhostname, localhost.$mydomain, localhost relay_domains = proxy:mysql:/etc/postfix/mysql-relay_domains_maps.cf # mail delivery recipient_delimiter = + # mappings alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases transport_maps = hash:/etc/postfix/transport #local_recipient_maps = # virtual setup virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_alias_maps.cf, regexp:/etc/postfix/virtual_regexp, virtual_mailbox_base = /var/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains_maps.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_maps.cf virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf virtual_minimum_uid = 101 virtual_uid_maps = static:101 virtual_gid_maps = static:12 virtual_transport = dovecot dovecot_destination_recipient_limit = 1 # debugging debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5 # authentication smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_local_domain = $myhostname broken_sasl_auth_clients = yes smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth # tls config smtp_use_tls = yes smtpd_use_tls = yes smtpd_tls_security_level = may smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom smtp_tls_session_cache_database = btree:$data_directory/smtp_tls_session_cache # Change mail.example.com.* to your host name smtpd_tls_key_file = /etc/pki/tls/private/mail.domain.com.key smtpd_tls_cert_file = /etc/pki/tls/certs/mail.domain.com.crt smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt smtpd_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt # rules restrictions smtpd_client_restrictions = smtpd_helo_restrictions = smtpd_sender_restrictions = smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_recipient_domain,check_policy_service unix:private/spfpolicy # uncomment for realtime black list checks # ,reject_rbl_client zen.spamhaus.org # ,reject_rbl_client bl.spamcop.net # ,reject_rbl_client dnsbl.sorbs.net smtpd_helo_required = yes unknown_local_recipient_reject_code = 550 disable_vrfy_command = yes smtpd_data_restrictions = reject_unauth_pipelining # Other options # email size limit ~20Meg message_size_limit = 204800000 mailbox_size_limit = 2048000000 # Vacation Scripts vacation_destination_recipient_limit = 1 recipient_bcc_maps = proxy:mysql:/etc/postfix/mysql-virtual_vacation.cf smtpd_milters = inet:127.0.0.1:8891 non_smtpd_milters = $smtpd_milters milter_default_action = accept milter_protocol = 2 --------------------------------------------------------------------------------------------------- master.cf:- # # Postfix master process configuration file.

I'm sorry that I don't have the time to prowl through that configuration-file to find the problem for you, but the essence of the problem is that Postfix does not recognize the user or alias-name on the e-mail as being a valid one for this system. Most likely it is not doing the lookups that you intended, and/or it is referring to sources that are not set up correctly.
Refer line-by-line to the Postfix documentation for the "alias" and "virtual alias" settings. Be sure that you understand each of them, and that they are correct. Then, as necessary, look in the map-files and other map-sources that you have specified. All of these configuration controls are designed to address the "mail from god@heaven.org problem." Mail won't be handled if its addresses appear to be bogus. |
Thanks, For your time Sir:)
I didn't mention any ids to "alias" and "virtual alias" and Now it is not giving error, but mails are missing. It is going to receipent side, but after the reply from their side I can't found in my inbox or any other folder also. when I gave telnet test, It shown below output:- telnet localhost 25 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1...

Sir,
In the 2nd post I talked about the virtual alias, but the job of the virtual alias :- To redirect mail from one address to one or more addresses. To implement virtual alias domains where all addresses are aliased to addresses in other domains. suppose we have two domains sandeep.com and domain2.com. if domain2.com sends a mail to sandeep.com mail receiving with no issues. if sandeep.com sends mail to domain2.com is also fine reached to their end .but the problem is if sandeep.com send mail to domain2.com they are trying reply to that mail in that time it is not receiving without showing any error. |
