    Hi all,
    I am trying to add a 2nd domain to postfix on my existing debian server. I have followed the tutorial here: . Incoming emails should save a file in the virtual folder structure, but nothing happens. When I revert to the old user based setup the emails get saved as a file which I would also expect after following the tutorial.

    postconf -n:
    allow_percent_hack = no
    append_at_myorigin = no
    append_dot_mydomain = no
    biff = no
    broken_sasl_auth_clients = yes
    config_directory = /etc/postfix
    default_destination_concurrency_limit = 2
    home_mailbox = Maildir/
    inet_interfaces = all
    mailbox_size_limit = 0
    message_size_limit = 104857600
    mime_header_checks = regexp:/etc/postfix/mime_header_checks
    mydestination =, localhost.localdomain, servername, localhost
    myhostname = localhost
    mynetworks = [::ffff:]/104 [::1]/128
    myorigin = /etc/mailname
    readme_directory = no
    recipient_delimiter = +
    relayhost =
    smtp_sasl_security_options = noanonymous
    smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
    smtpd_delay_reject = yes
    smtpd_helo_restrictions = reject_invalid_hostname
    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_relay_domains
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_authenticated_header = yes
    smtpd_sasl_local_domain = $myhostname
    smtpd_sasl_path = private/auth
    smtpd_sasl_type = dovecot
    smtpd_sender_restrictions = reject_unknown_address
    smtpd_tls_cert_file = /etc/ssl/certs/postfix.pem
    smtpd_tls_key_file = /etc/ssl/private/postfix.key
    smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
    smtpd_use_tls = yes
    swap_bangpath = no
    unknown_local_recipient_reject_code = 550
    virtual_gid_maps = static:1000
    virtual_mailbox_base = /home/vmail/vmail
    virtual_mailbox_domains = /etc/postfix/vhosts.txt
    virtual_mailbox_maps = hash:/etc/postfix/vmaps.txt
    virtual_uid_maps = static:1005
    I am not getting any error messages. Any ideas why incoming emails are not saved?

    Can you show the lines that appear in your postfix logfile[1] while you try to send an email which is not saved?
    [1] depends on your system, probably /var/log/mail.log

    Doublecheck the contents of

    If you are just starting, I would recommend you to have a look at mailcow. (

    Thanks Steini
    The issue is solved, I should have paid more attention to the logs. The virtual_mailbox_limit was sooo small that even a simple test email got rejected.
