    Hi to all, im a newbie on this Forum.
    Will appreciate all help and assistance on my problem.

    I setupped a mail server and i can receive mail on my domain, But cannot send email from any other domains. I followed the "Howto: ISP-style Email Server..." by Christoph Haas.



    ##my postconf -n
    alias_database = hash:/etc/aliases
    alias_maps = hash:/etc/aliases
    append_dot_mydomain = no
    biff = no
    broken_sasl_auth_clients = yes
    config_directory = /etc/postfix
    content_filter = smtp-amavis:[127.0.0.1]:10024
    inet_interfaces = all
    mailbox_size_limit = 0
    mydestination = hostname.mydomain.com, localhost.mydomain.com, localhost
    myhostname = hostname.mydomain.com
    mynetworks = 192.168.1.0/24
    myorigin = /etc/mailname
    receive_override_options = no_address_mappings
    recipient_delimiter = +
    relayhost =
    smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
    smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
    smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_path = private/auth
    smtpd_sasl_type = dovecot
    smtpd_tls_auth_only = yes
    smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem
    smtpd_tls_key_file = /etc/ssl/private/postfix.pem
    smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
    smtpd_use_tls = yes
    virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf,mysql:/etc/postfix/mysql-email2email.cf
    virtual_gid_maps = static:5000
    virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
    virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
    virtual_transport = dovecot
    virtual_uid_maps = static:5000
    ###end




    When i try to use MS outlook and send email from outside my home network, to 3 recipients at different domains, it wont send and has an error message that: "...- Sending reported error (0x800CCC80) : None of the authentication methods supported by this client are supported by your server"

    ##my mail.log
    dovecot: pop3-login: Login: user=<me@mydomain.com>, method=PLAIN, rip=87.5.144.18, lip=192.168.1.4
