    All necessary services seem to be running, it receives email from the sending server but the it deffers the mail being delivered to the mailbox because of initial server greeting? Or perhaps amavisd?

    Need help on this one.

    I think i know what the problem is, but i'm unsure how to resolve it.

    I have 2 public IP's on my machine so i set the smtp_bind_address in main.cf

    Apperantly postfix now tries to connect from the specified public IP to amavis.
    But amavis doesn't allow that, it only allows connections from localhost.

    This is what get's logged in the maillog:

    amavis[21502]: (!)DENIED ACCESS from IP mypublicIP, policy bank ''

    Sorry for spamming this topic. instead of using smtp_bind_address i have set the inet_interfaces to only use localhost and the IP i want to use for postfix. Now incoming email is working properly.

    But will this also make sure outgoing e-mail is always sent from that single public IP? faqforge is stating we need to use smtp_bind_address but apperantly that cannot be use combined with amavis, perhaps worth mentioning on the site?

    I tried other solutions in amavisd.conf:
    adding:

    $inet_socket_bind = undef; # binds to all IP interfaces if undef
    @inet_acl = qw( 127.0.0.1 [::1] x.x.x.40/32 );

    But that didn't work either in combination with the smto_bind_address set.
    Hopefully this will help some people when they are looking for an answer next time.

    Got it to work including the smtp_bind_address!

    first edit /etc/amavisd.conf

    To allow connections from the IP you have set as smtp_bind_address add:
    Code:
    @inet_acl = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10 IP4/32 ); 
    
    And then to bind amavisd to all listen to all interfaces:
    Code:
    $inet_socket_bind = undef;
    
    Now we also need to set that amavisd resends the scanned e-mail to the correct interface because we later will specify this in the master.cf file

    Uncomment the existing lines and add your IP4
    Code:
    $notify_method  = 'smtp:[IP4]:10025';
    $forward_method = 'smtp:[IP4]:10025';
    
    Now we edit main.cf to make the return and scanned mail send listen on the IP4:
    Code:
    amavis unix - - - - 2 smtp
            -o smtp_data_done_timeout=1200
            -o smtp_send_xforward_command=yes
    
    IP4:10025 inet n - - - - smtpd
            -o content_filter=
            -o local_recipient_maps=
            -o relay_recipient_maps=
            -o smtpd_restriction_classes=
            -o smtpd_client_restrictions=
            -o smtpd_helo_restrictions=
            -o smtpd_sender_restrictions=
            -o smtpd_recipient_restrictions=permit_mynetworks,reject
            -o mynetworks=IP4
            -o strict_rfc821_envelopes=yes
            -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks
            -o smtpd_bind_address=IP4
    
    Afterwards we can add smtp_bind_address in /etc/postfix/main.cf
    This will work combined with amavis.
