Hi

I'm working on a setup where my postfix who's receiving the domains, is
deciding on basis of a transport_maps if mail should be spam scanned or
not...

therefor i modified some satements in the amavis-postfix howto...
master.cf now looks like this

smtp inet n - n - - smtpd
        -o relay_domains=hash:/usr/local/postfix-data/relay_domains
        -o relay_recipient_maps=hash:/usr/local/postfix-data/relay_addresses
        -o transport_maps=hash:/usr/local/postfix-data/transportmap
        -o disable_dns_lookups=yes ## added this but result is the same

127.0.0.1:10025 inet n - n - - smtpd
        -o virtual_mailbox_domains =
hash:/usr/local/postfix-data/virtdomains
        -o virtual_mailbox_base = <blabla>
        -o virtual_mailbox_maps = hash:/usr/local/postfix-data/virtaddresses
        -o virtual_alias_maps = hash:/usr/local/postfix-data/virtalias
        -o virtual_uid_maps = static:5000
        -o virtual_gid_maps = static:5000
        -o mailbox_command_maps = hash:/usr/local/postfix-data/localmailers
        -o content_filter=
        -o local_recipient_maps=
        -o relay_recipient_maps=
        -o smtpd_restriction_classes=
        -o smtpd_delay_reject=no
        -o smtpd_client_restrictions=permit_mynetworks,reject
        -o smtpd_helo_restrictions=
        -o smtpd_sender_restrictions=
        -o smtpd_recipient_restrictions=permit_mynetworks,reject
        -o smtpd_data_restrictions=reject_unauth_pipelining
        -o smtpd_end_of_data_restrictions=
        -o mynetworks=127.0.0.0/8,<localip>/24
        -o smtpd_error_sleep_time=0
        -o smtpd_soft_error_limit=1001
        -o smtpd_hard_error_limit=1000
        -o smtpd_client_connection_count_limit=0
        -o smtpd_client_connection_rate_limit=0
        -o
receive_override_options=no_header_body_checks,no_unknown_recipient_checks

what I want to achieve is this: mail gets recieved by the daemon on port
25. For every domain I host, I make sure we just relay for. Then the
transport_maps are used to decide if uservirthost.com should be
filtered (sent to amavis) or not (sent to port 10025) directly. the
daemon 10025 does the translation, the :25 daemon does just relaying.

But i keep getting the "mail loops back to me" messages on :25...
Also I noted that the relay_recipients is just ignored, when sending
manual smtp commands, the process get just beyond the rcpt to:, while
it's not supposed to...

any thought here? the stuff in main.cf seems rather standard to me...

thanks
Arne
