    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?

    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?
