[Xtracted]

I just noticed that mail sent to an email adress on one of my sites get caught by my main server sites catch all email adress. The adress exists and should work without any problem.. Any suggestions of where I start looking?

I dont even have the variable $mydomain in that file..

Please post the content of your main.cf file, comments stripped.

The best solution is to get a "technical" domain that you don't use for web sites and email, but for naming your servers only.
You'd then give your server a hostname in that domain and use that hostname for myhostname and mydomain in /etc/postfix/main.cf.

And a subdomain would not work for this?

A subdomain is fine too as technical domain.

I created a subdomain, host.mydomain.se and modified main.cf so it looks like this:

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

append_dot_mydomain = no

smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

myhostname = host.mydomain.se
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
#mydestination = host.mydomain.se, localhost.mydomain.se, , localhost
relayhost =
mynetworks = 127.0.0.0/8
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
smtpd_sasl_local_domain =
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
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

virtual_maps = hash:/etc/postfix/virtusertable

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


My catch all on the domain I used to have before I changed it to host.mydomain.se still catches all emails outside that domain.. inside that domain it works fine..

What's in /etc/mailname?

[Xtracted]

A-ha! That seems to have done it.. exellent, thank you!

Do I need to change the server hostname in other files as well or will this do it?

No, you don't. :)
