    I have homeserver (homeserver.dyndns.org)
    and a dedicated server nr2.myserver.com (ispconfig 3 server)

    As my provider blocks sendingmail from port 25 I want homeserver sending mail over nr2 on port 587.
    Mail is already going to nr2 but still Relay access denied (in reply to RCPT TO command)) error

    Is it posible to add homeserver.dyndns.org to mynetworks or is there an other workaround to send this mail to nr2?

    Why do you have relayhost two time ...

    relayhost =
    mynetworks = 127.0.0.0/8,192.168.0.0/24,82.161.100.146
    mailbox_command = procmail -a "$EXTENSION"
    mailbox_size_limit = 0
    message_size_limit = 0
    recipient_delimiter = +
    inet_interfaces = 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
    smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd
    smtp_always_send_ehlo = yes
    relayhost = [nr2.myserver.com]:587


    use only one configuration like this ..

    relayhost = nr2.myserver.com:587

    are you sure you are allowed to send mail without authentication..

    same things was working on port 25 ?

    before it was possible to mail directly from homeserver
    so now changing it the way I described on top

    if you are able to send mail from command line..

    telnet nr2.myserver.com 587

    then surly you are not allowed to relay mails for your server.

    nope, also not possible by commandline.

    But I can configure nr2 too, thats why I asked if it is possible to add an host to mynetworks
