    Default Disclamimer trouble

    Am having trouble getting the disclaimer to work still!

    If I use the basic version, which assigns the disclaimer to both inwards and outwards travelling message I have no trouble. I have setup both a plain text and html version of my disclaimer message and they both work fine.
    However, when I try to use the version which just assigns it to outgoing messages I can not get it to work!

    This is my going by the Wiki instructions, ( is the external network address of my Zimbra server);

    -o smtpd_client_connection_rate_limit=0
    -o receive_override_options=no_header_body_checks,no_ unknown_recipient_checks,no_address_mappings

    This way, no disclaimer is displayed on either out or in mail. If I put the;
    -o content_filter=dfilt:
    line next to the first line like this; inet n - n - - smtpd
    -o content_filter=dfilt

    Then I get the disclaimer on both in and out mail, I also get this if I put the disclaimer against both lines like this; inet n - n - - smtpd
    -o content_filter=dfilt: inet n - n - - smtpd
    -o content_filter=dfi

    Because obviously this would be putting it on both in and out mail.

    What am I doing wrong? I have put the dfilt line further down but don't think it matters quite where it is as the disclaimer message does appear sometimes as stated above.

    Any help appreciated as I am getting hassled by my Boss to get this working!


    p.s. Spelt Disclaimer wrong at top, what a fool!

    Spotted this on a search for info about disclaimers and thought I'd add what I'd discovered, in case you haven't found a solution and our cases are similar...

    I made the same changes and couldn't get any outgoing disclaimers, then it dawned on my that by using the filter on it'd only run it through alterMime if it was sent via. localhost, in otherwords, the AJAX client. Anything sent using an external client, like Thunderbird, would hit the address of eth0, in your case, and append nothing.

    I followed the advice of the other topic you posted in regarding this, and added another IP - you can use a virtual interface if you need to , I have the luxury of 4 NIC's on this box :-)

    I ended up with the following at the top of my

    Code:    inet  n       -       n       -       -       smtpd   -o content_filter=dfilt:    inet  n       -       n       -       -       smtpd    inet  n       -       n       -       -       smtpd   -o content_filter=dfilt:
    ...where is the address my users mail clients point to for SMTP and is where my firewall forwards port 25 to. Works for me.

    Thanks Kev.

    I thought about doing that but the post said there no was no longer any need to do it this way so I thought it was just me!

    I have two NIC's in the Server so i'll give it a go later.

    Can confirm that this works with a Virtual network card address!

    It's a shame that all internal mail still gets the disclaimer but I can live with that!

    Thanks Kev
