Problem in email receiving

[bzzik]

Hi guys!

I just noticed very strange behavour of mail-server. I will try to explain:

We host several domains, for example let it be domain1.com, domain2.com, domain3.com. All domains have different email addresses: info@domain1.com, domain2@domain2.com, support@domain3.com. So when someone sends email to info@domain3.com (note, this address does not exist) it will come to info@domain1.com inbox! When someone sends email to info@domain2.com it also comes to info@domain1.com inbox!

Why? What is wrong with configuration of my server? Here is my postfix config:

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix
mydomain = mydomain.lv
inet_interfaces = all
unknown_local_recipient_reject_code = 550
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
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
sendmail_path = /usr/sbin/sendmail.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = no
manpage_directory = /usr/share/man
sample_directory = /usr/share/doc/postfix-2.3.3/samples
readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
smtpd_sasl_local_domain = s2.mydomain.lv
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_sasl_authenticated_header = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination
mynetworks = 127.0.0.0/8
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtpd_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
myhostname = s2.mydomain.lv
home_mailbox = Maildir/
mailbox_command =

virtual_maps = hash:/etc/postfix/virtusertable

mydestination = /etc/postfix/local-host-names

message_size_limit = 40960000

Thanks falko!

But what should I use for mydomain in this case? Cause my main domain is mydomain.lv and we have many email addresses like name@mydomain.lv and I do not want to lose them.

You could rename your server, e.g. buy a "technical" domain that you use solely for the purpose of naming your servers, but not for web sites and email.

Oh... Sad. No other way? For me it's sounds so stupid to buy more domains to host mail server...

Well, you just need one domain for all your servers, and it doesn't cost the world.
You can then name your servers server1.example.com, server2.example.com, etc. No need to buy one extra domain per server.
