Hi Stan,
thanks a lot for your eMail und sorry for the inconvenience. Here is the
hundred feet back down big picture: :-)
Postfix 2.5 on ubuntu 8.04.4. One physical interface with two public IPs.
eth0 -> 10.0.0.1 -> needs relay (with auth) for abc.com, def.com, ghi.com
to myIp.dyndns.org
eth0 -> 10.0.0.2 -> needs relay (with auth) for * (all) to
wp180.webpack.hosteurope.de (runs later on localhost only, therefore no
open relay)
I currently have:
master.cf:
smtp inet n - - - - smtpd <- uses
main.cf if think
127.0.0.1:25 inet n - n - - smtpd
-o content_filter=smtp:[wp180.webpack.hosteurope.de:25]
-o smtp_sasl_auth_enable=yes
-o smtp_sasl_password_maps=hash:/etc/postfix/sasl_gr_smarthost
-o relayhost=wp180.webpack.hosteurope.de:25
main.cf:
myhostname = mx0.mydomain.com
myorigin = $myhostname
mydestination =
relay_domains = hash:/etc/postfix/transport
relayhost = myIp.dnsalias.org
transport_maps = hash:/etc/postfix/transport
relay_recipient_maps = hash:/etc/postfix/valid_recipients
virtual_alias_maps = hash:/etc/postfix/virtual_recipients
##postmap hash:/etc/postfix/...
show_user_unknown_table_name = no
mailbox_command =
mailbox_size_limit = 0
inet_protocols = all
inet_interfaces = 10.0.0.1
parent_domain_matches_subdomains =
debug_peer_list,
smtpd_access_maps
smtpd_recipient_restrictions =
permit_mynetworks
reject_unauth_destination
smtpd_sender_restrictions = reject_unknown_sender_domain
unknown_address_reject_code = 554
Is this setup possible with postfix?
Thanks a lot in advance!
