Default mail relay

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

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.
